OK.
What about a convenience function that returns all three pointers and pitches
in an array?
Also, passing the config is enough, as we are passing pointer/pitch already,
this is very
important when you have the buffer or allocation only, the surface might be
destroyed by that
time, or the surface might already have another config, that's why the config
gets copied into
buffers/allocations when they are created from surface.
get_ ( const CoreSurfaceConfig * const config,
const void * const data,
int pitch,
int x,
int y,
unsigned int num, <=== should be 1, 2 or 3 as
limit for output arrays
u8 ** pointers,
int * pitches )
