NAME
       plsmema - Set the memory area to be plotted (RGBA)


SYNOPSIS
       plsmema(maxx, maxy, plotmem)


DESCRIPTION
       Set  the  memory area to be plotted (with the memcairo driver) as the dev member of the stream structure.
       Also set the number of pixels in the memory passed in plotmem, which is a block of memory maxy by maxx by
       4 bytes long, say: 480 x 640 x 4 (Y, X, RGBA)

       This memory will have to be freed by the user!

       Redacted form: plsmema(maxx, maxy, plotmem)

       This function is not used in any examples.


ARGUMENTS
       maxx (PLINT(3plplot), input)
              Size of memory area in the X coordinate.

       maxy (PLINT(3plplot), input)
              Size of memory area in the Y coordinate.

       plotmem (PLPointer(3plplot), input)
