Thanks for the info. I see it is a descendant of PBear.com code. I
remember using that back in 1998. :)

I took a quick look at the code in general and was truly disappointed.
Quick examples:
===========[HtmlImages.pas]====================
uses
{$ifdef LCL}
LclIntf, IntfGraphics, FpImage, LclType, LResources, LMessages, HtmlMisc,
{$else}
Windows, Jpeg,
{$endif}
SysUtils, Classes, Graphics, Forms,
Controls,
===============================
...or...
===========[HTMLSubs.pas]====================
uses
{$ifdef UseInline}
HtmlCaches,
{$endif}
{$ifdef VCL}
Windows,
{$ifndef Compiler28_Plus}
EncdDecd,
{$endif}
{$endif}
Messages, Graphics, Controls, ExtCtrls, Classes, SysUtils, Variants,
Forms, Math, Contnrs, ComCtrls,
{$ifdef LCL}
LclIntf, LclType, HtmlMisc, types,
{$endif}
HtmlGlobals,
===============================
...or...
===========[ReadHTML.pas]====================
uses
{$ifdef LCL}
LclIntf, LclType, HtmlMisc,
{$else}
Windows,
{$endif}
SysUtils, Math, Variants, Classes, Graphics, Controls, Contnrs,
HtmlGlobals,
===============================
Those dependencies are crazy! LCLIntf, Forms, Graphics, Controls,
Windows (???) all in a unit that just reads and parses HTML. Wow.
Sadly TurboPower IP doesn't look any better - at least the version
included with Lazarus.
My plan is to develop a 100% non-GUI-toolkit-dependent browser engine,
which is 100% doable. The only (optional) GUI toolkit dependency would
be the rasterizer integration for LCL or fpGUI - the last step in the
engine pipeline. But if you render to an image file for example (via
FPImage or AggPas), their would be no GUI toolkit dependency.
