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.
