-/** Premultiplied Alpha (PMA) Blending algorithm.
-Assumes src and target pixels are in PMA format (i.e., the color channels are already multiplied
-with the alpha channel.
-Blending Equations:
-Cd' = Cs + ((255 - As) * Cd)/255
-Ad' = As + ((255 - As) * Ad)/255
-where Cd' and Ad' are destination values for color and alpha channels respectively, after blending,
-Cd and Ad are destination values before blending, and Cs and As are source values (color and
-alpha values respectively).
-Optimisations:
-Use of 256 instead of 255 converts the division to shift (faster).
-Red and Blue channels are calculated together in one 32 bit operation.
-Alpha and Green channels are calculated in the same way. However, due the
-position of these channels within the pixel format, an extra shift is required.
-The equations used are:
-Cd' = Cs + (((0x100 - As) * Cd)>>8)
-Ad' = As + (((0x100 - As) * Ad)>>8)
-For the results to not overflow, it is required that the value of any of the color channels
-is no greater than the alpha channel, which is what is exepected of pma format.
-It is also assumed that the aMask is equal to source alpha.
-@param 	aDestPixel	The destination pixel value.
-@param	aSrcPixel	The source pixel value.
-@param	aMask		The source alpha. It is assumed to be same as source alpha.
-@return the alpha-blended pixel (within the PMA space).
