Summary0023632: Add support for NPOT mipmap textures in TKOpenGl
DescriptionThis is desired to use automatic generation of mipmap levels for NPOT (not-power-of-two) textures when supported by hardware (glGenerateMipmap function available since OpenGL 3.0 or within GL_ARB_framebuffer_object extension).

Current implementation supports mipmap generation using gluBuild2DMipmaps which always performed on CPU and scale image to POT dimensions.
