c827ea3a68 0024381: Visualization, TKOpenGl - revise matrices stack and usage of temporary matrices
0025301: Visualization, TKOpenGl - transpose matrix manually before glUniformMatrix4fv()

OpenGl_View::ReleaseGlResources() - release GL resources of trihedron, do not destroy it

8625ef7e94 0025282: Visualization, OpenGl_PrimitiveArray - provide built-in GLSL programs as alternative to FFP
Enumerations Visual3d_TypeOfModel, V3d_TypeOfShadingModel.
- Remove unused values V3d_MULTICOLOR, V3d_HIDDEN, Visual3d_TOM_INTERP_COLOR.
- Add per-pixel shading mode - V3d_PHONG, Visual3d_TOM_FRAGMENT.

Draw Harness command vrenderparams.
Add option -shadingModel to setup Shading Model.

OpenGl_Caps::ffpEnable - new option to switch FFP/built-in GLSL programs.
OpenGl_ShaderManager - add built-in GLSL programs.

Draw Harness command vcaps.
- Fix command syntax to meet coding rules.
- Add option -ffp to activate/disable built-in GLSL programs.

GLSL API changes.
- Rename vertex attribute occColor -> occVertColor.
- Introduce vec4 occColor uniform variable for light-less shaders.
- Introduce float occPointSize uniform variable for marker programs.

OpenGl_VertexBuffer::bindAttribute() - activate normalization for non-GL_FLOAT types,
since color attribute is defined as 32-bit vector of 4 unsigned byte values.

OpenGl_Context - add methods SetColor4fv() and SetPointSize()
for parameters redirection to active GLSL program
(as alternative to glColor4fv() and glPointSize()).

OpenGl_ShaderProgram - define default precision for float types
in Fragment Shader within OpenGL ES 2.0+ context.

OpenGl_AspectMarker, initialize Aspect_TOM_O_POINT display list
in the same way as sprite texture.

OpenGl_Texture, do not use sized internal formats on OpenGL ES.

7d3e64ef5e 0025213: Visualization, TKOpenGl - do not use deprecated built-ins in GLSL shaders
Inherit NCollection_Buffer from Standard_Transient, do not use incomplete NCollection_Handle.

OpenGl_Context, add methods ActiveProgram(),BindProgram()
to manage currently active GLSL program.
Add method ::ToUseVbo().

OpenGl_ShaderProgram, setup locations of pre-defined vertex attributes
occVertex, occNormal, occTexCoord, occColor before linkage.
Remove methods OpenGl_ShaderProgram::Bind(), ::BindWithVariables()
and ::Unbind() - OpenGl_Context::BindProgram() should be used instead.

Introduce class OpenGl_VertexBufferCompat, which emulates VBO
behavior on systems without VBO (compatibility with broken OpenGL drivers on Windows).

OpenGl_PrimitiveArray - use OpenGl_VertexBufferCompat when VBO is unavailable,
remove duplicated code. Use OpenGl_VertexBuffer::HasNormalAttribute()
method to activate lighting.

OpenGl_Text - use OpenGl_VertexBufferCompat, eliminate duplicated code.

Changes in OpenGl_VertexBuffer, drop methods BindFixed()/UnbindFixed().
Superseded by new methods BindAllAttributes()/UnbindAllAttributes()
which handle active GLSL program, when it is set.

10b9c7dfc0 0025133: TKOpenGl - Crash on closing a view containing presentations with capping
OpenGl_Element destruction and resource deallocation methods now accept
a pointer to OpenGl_Context instead of a handle to avoid double deletion
of the context.

d5f74e42d6 0024624: Lost word in license statement in source files
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.

1238134135 0024310: TKOpenGl - GLSL compatibility issues
Lights defintion clean up:
- remove duplicated enumeration TLightType (equals to Visual3d_TypeOfLightSource)
- remove unused fields from Graphic3d_CLight
- OpenGl_Light, reuse Graphic3d_CLight definition

Phong GLSL program:
- move out cumulative ambient light intencity from limited list of lights
- compatibility issues, replace array of structures (light sources, materials, clipping planes) with arrays of primitive types

New Draw Harness command vlight to alter light sources definition.

OpenGl_ShaderProgram::Initialize() - add missing Linker log
