Summary0021091: Text rendering based on FTGL library
DescriptionThe main advantage of this improvement is a preparation platform for future
integration of visualization functionality with using C++ features.
It will allow to reorganize visualization algorithms and other auxiliary
functionality to more clear and flexible architecture.

The main planned future integration is a support external libraries for advanced
2D and 3D text visualization.
Additional information
and documentation updates		Documentation remark, added by PSN 2010-01-28 14:27:10:

New features:
- Implementation of LayerItems for Visual3d_Layers. This approach of
visualization of 2D layer presentations. Each Item has a two typical for
presentation virtual methods: ComputeLayerPrs and RedrawLayerPrs.
ComputeLayerPrs calls by hand or before RedrawLayerPrs if IsNeedToRecompute flag
is true. This approach for visualization of Layer content helps to remove
limitation ofOpenGl lists ( uses in Layers by default ). Old functionality is
not changed.

- First implementation of support of system fonts. This functionality parses
system configuration and searches all system fonts. This information will use in
future implementation of text 2D and 3D presentations.

Improvements:
- Default text (or font) height of Prs3d presentation is not a magic constant
for all graphic drivers yet (1/81). Graphic3d_GraphicDriver now has a virtual
method ::DefaultTextHeight() with returns adopted parameter for current Graphic
Driver. Use '-1' for default representation.

- New text output representation is implemented in OpenCascade text
drawing. This functionality to use system fonts as an alternative texture
mapped fonts(WNT) or traditional bitmap fonts(UNIX, SUN). This is new feature
makes text output owing to the fact that system used FTGL and FreeType
libraries.
- Text output on Viewer several times faster. This is important for
applications dealing with large number of text labels in Viewer.
- New functionality is control basic Font properties(FontName,
FontAspect, Height, Align, Incline, Color, Zoomable). If user introduce
FontName, which not meet in System font list, then algorithm return default
font- “Courier”. Zoomable is answered for increase or decrease font(as object).
Incline is allowed to user bending text(in degrees). Align is displaced font
relatively of it associating point.

Changes:
OpenGl package is migrated to C++ compiler:
- redesign memory management functionality;
- redesign stack of graphic structures functionality.

Removed deprecated functionality from Graphic3d_GraphicDriver (all duplicates of
OpenGl_GraphicDriver functionality).

Redesigned InterfaceGraphic package

Add text draw command: vdrawtext. This command is allowed controlled Base font
functionality.
