kgv f978241fb6 0025556: Visualization - support stereo pair formats recognized by consumer display devices
Graphic3d_StereoMode - add new enumeration for stereoscopic outputs:
- Graphic3d_StereoMode_QuadBuffer
- Graphic3d_StereoMode_Anaglyph
- Graphic3d_StereoMode_RowInterlaced
- Graphic3d_StereoMode_ColumnInterlaced
- Graphic3d_StereoMode_ChessBoard
- Graphic3d_StereoMode_SideBySide
- Graphic3d_StereoMode_OverUnder

Graphic3d_RenderingParams - add new options controlling stereo output:
- StereoMode
- ToReverseStereo
- AnaglyphFilter

OpenGl_ShaderManager - add predefined GLSL programs for new stereo outputs.
OpenGl_Workspace::Redraw() - do not implicitly disable stereo to allow stereo dump as is.
OpenGl_Caps - add flag swapInterval to control VSync.
OpenGl_Workspace::BufferDump() - handle cases with non-applicable GL_PACK_ROW_LENGTH.

CALL_DEF_WINDOW - drop unused fields; add fields "left" and "top"
to reverse stereo pair for interlaced output depending on window position.

Draw Harness, ViewerTest:
- Extend syntax of command vstereo to setup stereo.
- Extend vdump command to allow dump of stereoscopic pair in different formats.
- Extend command vcaps with option vsync.
- Use mouse scroll to zoom and adjust ZFocus in WinAPI.
- Use "/" and "*" to adjust IOD.

v3d/glsl/stereo - add test case for stereo modes.

Cocoa_LocalPool, OSD_EnvironmentIterator - fix compilation issues on OS X Snow Leopard.
