 *
 * 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);
