* kQAAntiAlias_Fast. The driving software should continue to use the alpha fields
* for transparency even when antialiasing is being used (the drawing engine will
* resolve the multiple blending requirements as best as it can).

* Macro definition for easily setting the texture priority bits in the flags field of
* QATextureNew(), and QABitMapNew().
*
* The priority value must be a number between 0 and 15. 0 is top priority, and 15 is lowest
* priority. Note that this is different than OpenGL which uses floats from 0.0 to 1.0 where
* 1.0 is top priority. In RAVE, this system is more like texture ranking, thus 0 is top rank,
* and 15 is the last ranking.
*
* Texture prioritization is mainly used for systems which support AGP memory. This allows the
* hardware driver to determine which textures to put into faster VRAM and which to put into
* slower AGP RAM. If you dont care about texture priority, then you dont need to worry about
* this macro or the priority bits since the default will always be top priority when all 4 bits
* of this flag field are 0's.
*
* To upload a texture with high priority, do the following:
*
* unsigned long flags = kQATexture_Mipmap; // Initialize flags
*
* flags |= QACalculatePriorityBits(0); // Setting top priority (this actually does
* // nothing since the bits are still 0000)
* QATextureNew(myEngine, flags, pixelType, image, &raveTexture);
*
*
* To do a texture with a middle priority of 8, do the following:
*
* unsigned long flags = kQATexture_HighCompression; // Initialize flags
*
* flags |= QACalculatePriorityBits(8); // Setting middle priority
*
* QATextureNew(myEngine, flags, pixelType, image, &raveTexture);
