Which: which position in the range to get. pLeft and pTop return 0, pBottom and pRight return Range.
Where: percentage or pixels for Which = pPercentage resp. pDim.
Range: the range in which the result can vary.

Tiled: if false returns a TiledEnd according to unmodified Pos, that allows to pass the tiling
process and depending on the visibility of the object in the cliparea the untiled object is
processes at most once. If true, Pos is moved to a position between ClipMin - ObjectSize and
ClipMin so that the tiling process will put one of the tiles to original Pos.
TileAreaMin, TileAreaMax: the area in with the object is to tile.
TileSize: the size of the tile.
Pos: on input: the position to consider for tiling. on output the new position shifted by multiples
of the object size to where the object covers the tile area minimum.
TiledEnd: a position on and after which no more tiles are processed.

PRec has the CSS information on the background image, it's starting location and
whether it is tiled in x, y, neither, or both.
ARect is the cliprect, no point in drawing tiled images outside it.
XOff, YOff are offsets which allow for the fact that the viewable area may not be at 0,0.
IW, IH are the total width and height of the document if you could see it all at once.
BW, BH are bitmap dimensions used to calc tiling.
X, Y are the position (window coordinates) where the first background iamge will be drawn.
X2, Y2 are tiling limits. X2 and Y2 may be such that 0, 1, or many images will
get drawn. They're calculated so that only images within ARect are drawn.

// some failure cases, write operations issued with weak write concerns may
// not persist. With stronger write concerns, clients wait after sending a
// write operation for MongoDB to confirm the write operations. MongoDB
// provides different levels of write concern to better address the specific
// needs of applications. Clients may adjust write concern to ensure that
// the most important operations persist successfully to an entire
// MongoDB deployment. For other less critical operations, clients can
// adjust the write concern to ensure faster performance rather than
// ensure persistence to the entire deployment.
// - wcAcknowledged is the default safe mode: the mongod confirms the
// receipt of the write operation. Acknowledged write concern allows clients
// to catch network, duplicate key, and other errors.
// - with wcJournaled, the mongod acknowledges the write operation only
// after committing the data to the journal. This write concern ensures that
// MongoDB can recover the data following a shutdown or power interruption.
// - wcReplicaAcknowledged will guarantee that the write operation propagates
// to at least one member of a replica set
// - with wcUnacknowledged, MongoDB does not acknowledge the receipt of
// write operation. Unacknowledged is similar to errors ignored; however,
// drivers attempt to receive and handle network errors when possible. The
// driver's ability to detect network errors depends on the system's
// networking configuration.
// - with wcErrorsIgnored, MongoDB does not acknowledge write operations.
// With this level of write concern, the client cannot detect failed write
// operations. These errors include connection errors and mongod exceptions
// such as duplicate key exceptions for unique indexes. Although the errors
// ignored write concern provides fast performance, this performance gain
// comes at the cost of significant risks for data persistence and durability.
// WARNING: Do not use wcErrorsIgnored write concern in normal operation.

// MAJOR CHANGES
05-January-20001
GI: Major code reorganization and polishing
31-May-2000
GI TunnelHeaders eliminated. Some other code jugling.
29-May-2000
GI Components split in several files to be more compliant
with Indy coding standards.
It consists of:
- IdTunnelHeaders
- IdTunnelCommon
- IdTunnelMaster
- IdTunnelSlave
24-May-2000
GI: Turbo translation mode finished (01:24). It works!
Will draw icons in the morning.
23-May-2000
GI: Turbo translation mode to Indy standard started by
Gregor Ibic (hehe) (now is 23:15)

*
* CHANGES:
* v1.2
* + support of currency data type
* + right trim unquoted string
* + read Unicode Files and streams (Litle Endian with BOM)
* + Fix bug on javadate functions + windows nt compatibility
* + Now you can force to parse only the canonical syntax of JSON using the stric parameter
* + Delphi 2010 RTTI marshalling
* v1.1
* + Double licence MPL or LGPL.
* + Delphi 2009 compatibility & Unicode support.
* + AsString return a string instead of PChar.
* + Escaped and Unascaped JSON serialiser.
* + Missed FormFeed added \f
* - Removed @ trick, uses forcepath() method instead.
* + Fixed parse error with uppercase E symbol in numbers.
* + Fixed possible buffer overflow when enlarging array.
* + Added "delete", "pack", "insert" methods for arrays and/or objects
* + Multi parametters when calling methods
* + Delphi Enumerator (for obj1 in obj2 do ...)
* + Format method ex: obj.format('<%name%>%tab[1]%</%name%>')
* + ParseFile and ParseStream methods
* + Parser now understand hexdecimal c syntax ex: \xFF
* + Null Object Design Patern (ex: for obj in values.N['path'] do ...)
* v1.0
* + renamed class
* + interfaced object
* + added a new data type: the method
* + parser can now evaluate properties and call methods
* - removed obselet rpc class
* - removed "find" method, now you can use "parse" method instead
* v0.6
* + refactoring
* v0.5
* + new find method to get or set value using a path syntax
* ex: obj.s['obj.prop[1]'] := 'string value';
* obj.a['@obj.array'].b[n] := true; // @ -> create property if necessary
* v0.4
* + bug corrected: AVL tree badly balanced.
* v0.3
* + New validator partially based on the Kwalify syntax.
* + extended syntax to parse unquoted fields.
* + Freepascal compatibility win32/64 Linux32/64.
* + JavaToDelphiDateTime and DelphiToJavaDateTime improved for UTC.
* + new TJsonObject.Compare function.
* v0.2
* + Hashed string list replaced with a faster AVL tree
* + JsonInt data type can be changed to int64
* + JavaToDelphiDateTime and DelphiToJavaDateTime helper fonctions
* + from json-c v0.7
* + Add escaping of backslash to json output
* + Add escaping of foward slash on tokenizing and output
* + Changes to internal tokenizer from using recursion to
* using a depth state structure to allow incremental parsing
* v0.1
* + first release

(* Delphi Free Stuff Include File. This file is used for all my components *)
(* to create some standard defines. This will help reduce headaches when new *)
(* versions of Delphi and C++Builder are released, among other things. *)
(* **************************************************************************** *)
(* Brad Stowers: bstowers@pobox.com *)
(* Delphi Free Stuff: http://www.delphifreestuff.com/ *)
(* June 27, 2001 *)
(* **************************************************************************** *)
(* Usage: Add the following line to the top of your unit file: *)
(* {$I DFS.INC} *)
(* **************************************************************************** *)
(* *)
(* Complete Boolean Evaluation compiler directive is turned off by including *)
(* this file. *)
(* The $ObjExportAll directive is turned on if compiling with C++Builder 3 or *)
(* higher. This is required for Delphi components built in Builder with *)
(* run-time packages. *)
(* *)
(* Here is a brief explanation of what each of the defines mean: *)
(* DELPHI_FREE_STUFF : Always defined when DFS.INC is included *)
(* DFS_WIN16 : Compilation target is 16-bit Windows *)
(* DFS_WIN32 : Compilation target is 32-bit Windows *)
(* DFS_USEDEFSHLOBJ : The SHLOBJ.PAS version contains no none errors. *)
(* Delphi 2.0x and C++Builder 1.0x shipped with a *)
(* version of SHLOBJ.PAS that had many nasty errors. *)
(* See my web site in the Hints section for how to fix *)
(* DFS_NO_COM_CLEANUP : The version of the compiler being used does not *)
(* require COM objects to be released; it is done *)
(* automatically when they go "out of scope". *)
(* DFS_NO_DSGNINTF : Delphi 6 pretty much kills off the DsgnIntf unit *)
(* for good. Split into a couple of new units. *)
(* DFS_DESIGNERSELECTIONS: IDesignerSelections replaced TDesignerSelectionList *)
(* DFS_IPROPERTY : IProperty introduced for design-time stuff. *)
(* DFS_COMPILER_1 : Delphi 1.0 is the compiler. Note that C++B 1.0 *)
(* does NOT cause this to be defined. It is really *)
(* the 2.0 compiler. *)
(* DFS_COMPILER_1_UP : Delphi 1.0x or higher, or C++B 1.0x or higher is *)
(* the compiler. *)
(* DFS_COMPILER_2 : Delphi 2.0x or C++B 1.0x is the compiler. *)
(* DFS_COMPILER_2_UP : Delphi 2.0x or higher, or C++B 1.0x or higher is *)
(* the compiler. *)
(* DFS_COMPILER_3 : Delphi 3.0x or C++B 3.0x is the compiler. *)
(* DFS_COMPILER_3_UP : Delphi 3.0x or higher, or C++B 3.0x or higher is *)
(* the compiler. *)
(* DFS_COMPILER_4 : Delphi 4.0x or C++B 4.0x is the compiler. *)
(* DFS_COMPILER_4_UP : Delphi 4.0x or higher, or C++B 4.0x or higher is *)
(* the compiler. *)
(* DFS_COMPILER_5 : Delphi 5.0x or C++B 5.0x is the compiler. *)
(* DFS_COMPILER_5_UP : Delphi 5.0x or higher, or C++B 5.0x or higher is *)
(* the compiler. *)
(* DFS_COMPILER_6 : Delphi 6.0x or C++B 6.0x is the compiler. *)
(* DFS_COMPILER_6_UP : Delphi 6.0x or higher, or C++B 6.0x or higher is *)
(* the compiler. *)
(* DFS_UNKNOWN_COMPILER : No sense could be made of the compiliation *)
(* environment. *)
(* DFS_CPPB : Any version of C++B is being used. *)
(* DFS_CPPB_1 : C++B v1.0x is being used. *)
(* DFS_CPPB_3 : C++B v3.0x is being used. *)
(* DFS_CPPB_3_UP : C++B v3.0x or higher is being used. *)
(* DFS_CPPB_4 : C++B v4.0x is being used. *)
(* DFS_CPPB_4_UP : C++B v4.0x or higher is being used. *)
(* DFS_CPPB_5 : C++B v5.0x is being used. *)
(* DFS_CPPB_5_UP : C++B v5.0x or higher is being used. *)
(* DFS_DELPHI : Any version of Delphi is being used. *)

TODO: broadcast a message to several aCallingThread: THttpServerResp values
(add TWebSocketClientRequest? or asynch notifications may be enough, and
the "broadcast" feature should be implementation at application level,
using a list of callbacks)
TODO: enhance TWebSocketServer process to use events, and not threads
- current implementation has its threads spending most time waiting in loops
- eventually also at SynCrtSock's THttpServer class level also

Hi, to All:
...While recently "tuning up" one of my Programs I'm currently
working on, I ran a little test to Compare the perfomance
of the different versions of Turbo Pascal from 5.0 through
to 7.0. The results were quite suprizing, and I thought I'd
share this With you guys/gals.
Here are the results of a "sieve" Program to find all the primes
in 1 - 100,000, running on my AMI 386SX-25 CPU desktop PC:
CompILER EXECUTION TIME RELATIVE TIME FACtoR
==================================================
TP 7.0 46.7 sec 1.00
TP 6.0 137.8 sec 2.95
TP 5.5 137.5 sec 2.94
TP 5.0 137.6 sec 2.95
Running the same Program to find all the primes in 1 - 10,000,
running on my 8086 - 9.54 Mhz NEC V20 CPU laptop PC:
CompILER EXECUTION TIME RELATIVE TIME FACtoR
==================================================
TP 7.0 14.1 sec 1.00
TP 6.0 28.3 sec 2.00
notE: This would seem to indicate that the TP 7.0 386 math-
library is kicking in when run on a 386 CPU.
Here is the source-code to my "seive" Program:

...This little test would put TP 7.0's .EXE's between 2 to 3
times faster than TP4 - TP6 .EXE's. (I've found simmilar results
in testing other Programs I've written.) I guess this is one more
reason to upgrade to TP 7.0 .
...I'd be curious to see how StonyBrook's Pascal+ 6.1 Compares
to TP 7.0, in terms of execution speed With this Program.

simple BubbleSort will suffice.

If it's a bigger list than, say 100 or so elements, or it needs to be
sorted often, you'll probably need a better algorithm, like a shell sort
or a quicksort.
