/* Use conversion when the paletted texture extension is not available, or when it is available make sure it is used
* for texturing as it won't work for calls like glDraw-/glReadPixels and further also use conversion in case of color keying.
* Paletted textures can be emulated using shaders but only do that for 2D purposes e.g. situations in which the main render target uses p8. Some games like GTA Vice City use P8 for texturing which conflicts with this.
