Atualizamos a função richtext. Agora ela está completa.
Quando foi feita, não veio com a opção de imagens(estava comentado). gif, jpeg, png. toda essa parte era de uma lib (dll) do pessoal do fivewin.
Código: Selecionar todos

### Fixed
- **dialog.c**: fixed s_PSPProc() pushing pObject a second time instead
of the real lParam when dispatching WM_INITDIALOG for property sheet
pages. Confirmed harmless today - InitModalDlg() in hdialog.prg (the
handler property sheet pages route through, since pages are regular
HDialog objects) explicitly marks both wParam and lParam as
HB_SYMBOL_UNUSED - but any WM_INITDIALOG handler that started reading
lParam would have silently received the wrong value. Now pushes
lParam like every other message.

* contrib/misc/richtext.prg:
- Refactored Bmp2Wmf() to convert BMP files into Enhanced Metafiles (EMF)
using the library's native hwg_Createenhmetafile()

* contrib/misc/richtext.prg:
- Modernized Bmp2Wmf() method: replaced legacy DibRead/DibDraw with
HBitmap():LoadFromFile() and oBmp:Draw() to generate WMF metafiles
directly via GDI. Eliminates dependencies on obsolete DIB functions.
- Uses 8 KB buffer and hb_StrToHex() for fast binary conversion.
- Added screen DPI fallback and proper temporary file management.

* contrib/misc/richtext.prg:
- Added new Wmf2Rtf() method to embed Windows Metafiles (WMF) directly
into RTF documents. Extracts dimensions from the Aldus Placeable
Metafile header using native Harbour functions L2Bin() and Bin2W().
- Uses 8 KB buffer and hb_StrToHex() for fast binary-to-hex conversion.
- Eliminates dependency on GETBMETAFILE() and ::oPrinter.

* source/winapi/draw.c:
+ Added HWG_GDIPLUSSAVEPNG() C function to handle native GDI+ PNG stream
encoding, providing cross-platform 32/64-bit support (Clang/MSVC/GCC).
* contrib/misc/richtext.prg:
- Added new RtfImage() method to embed JPEG, PNG, and GIF images into RTF
documents using native Harbour/HWGUI functions.
GIF images are automatically converted to PNG via HWG_GDIPLUSSAVEPNG()
and embedded as PNG data (using \pngblip).
- Updated Image() method to call RtfImage() for all image formats except
BMP/WMF (which remain as stubs for future implementation).

* contrib/misc/richtext.prg:
- Added full Unicode (UTF-8) support.
Changed RTF header to code page 65001 and implemented \u escapes.
- Fixed shading normalization in Paragraph and IncStyle.
- Corrected style handling in ParaStyle and CharStyle (now use Len(::ParStyles)).
- Added validation for header data in DefNewTable.
- Updated all comments to English and improved code readability.
- Kept image inclusion methods as stubs (future enhancement).
