OpenGl_ShaderManager::pointSpriteAlphaSrc() now does not return alpha from Red channel for RGBA marker texture in Core profile. OpenGl_ShaderManager::prepareStdProgramFlat() - restored code for drawing points without texture. Built-in GLSL programs now flip .y in shaders instead of relying on GL_POINT_SPRITE_COORD_ORIGIN unavailable on OpenGL ES. Added sample markers.tcl (moved from test cases). Sample now includes marker_kr.png for testing marker orientation.
