0029076: Visualization - implement element shrinking Shader

Browse Source 
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.

OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).

Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default
and properly handled at TKOpenGl level - enables coverage for Graphic3d_AlphaMode_Mask primitives.

OpenGl_PrimitiveArray now uses GLSL programs instead of glPolygonMode() by default,
which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)
or stipple line style is required (not implemented within Face GLSL).

vaspects command has been extended by -setInterior -setDrawEdges -setEdgeColor -setEdgeType -setEdgeWidth
arguments replacing vsetinteriorstyle/vsetedgetype/vunsetedgetype commands.
vaspects now accepts arguments without "set" prefix.
ViewerTest::ParseColor() now parses RGBA color.

Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.
