-/* Define some macros which can expand into proxy functions between

- * 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.
