Map a region of this buffer for read or write access by the CPU.
Fetches data from the GPU if needed. This operation may be slow if cpu_readable_fast or cpu_writeable_fast are not true, or if the required colorspace is different from the internal one.
Note that if the buffer has Efl.Gfx.Buffer.buffer_borders, then x and y may be negative.
