0026122: Visualization, TKOpenGl - clipping and capping is broken when ffp is disabled on Linux

Browse Source 
OpenGl_Clipping - do not setup clipping planes using FFP when it is disabled.

OpenGl_ShaderManager - apply 2d texture coordinates transformation in GLSL programs.
OpenGl_Context::SetTextureMatrix() - move texture matrix assignment from OpenGl_Workspace::setTextureParams() to OpenGl_Context.

Add test case demo/samples/dimensionsglsl with FFP turned OFF.
Add test case v3d/glsl/texture_trsf applying texture transformation.

Small correction of test case for issue CR26122
