/* Define some macros which can expand into proxy functions between
* ARM assembly optimized functions and the rest of pixman fast path API.
*
* All the low level ARM assembly functions have to use ARM EABI
* calling convention and take up to 8 arguments:
* width, height, dst, dst_stride, src, src_stride, mask, mask_stride
*
* The arguments are ordered with the most important coming first (the
* first 4 arguments are passed to function in registers, the rest are
* on stack). The last arguments are optional, for example if the
* function is not using mask, then 'mask' and 'mask_stride' can be
* omitted when doing a function call.
*
* Arguments 'src' and 'mask' contain either a pointer to the top left
* pixel of the composited rectangle or a pixel color value depending
* on the function type. In the case of just a color value (solid source
* or mask), the corresponding stride argument is unused.
