number of pixels plotted
write the color value generated from a given color table of a rectangular array of pixels starting at a specified x,y location and continuing through to another x,y location within a certain RastPort
For each pixel in a rectangular region, write the color value generated with a given color lookup table from a linear array of indexed pixel values into the bitmap used to describe a particular rastport.
Attention
Does only work on rastports with depth > 8bits
The count value returned is totally wrong.
With cgxsystem.library up to version 41.19, the call returns immediately with CTABFMT_XRGB8 due to a bug in the code
