       gl_putboxmask  -  copy  a  masked  pixmap to a rectangular

       #include <vgagl.h>

       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_putbox-

       Pixmaps are in row-major order. The source  pixmap  memory
       has the size w * h * BYTESPERPIXEL.

       It  is  very  likely that both are at least to some extent
