gl_putboxmask - copy a masked pixmap to a rectangular area
void gl_putboxmask(int x, int y, int w, int h, void *dp);
Copy the contents of a memory buffer dp to a rectangular bitmap at
position (x, y) with size (w, h).
This function works like gl_putbox, but does not write pixmap pixels of
color zero. If the same pixmap is used often you should consider using
the faster gl_putboxmaskcompiled(3).
Pixmaps are in row-major order. The source pixmap memory has the size w
* h * BYTESPERPIXEL.
