Writes a pixel to a bitmap in a GrafCon's foreground color.
Err WritePixel (Item bitmapItem,GrafCon *gc,Coord x, Coord y)
This call writes a pixel to the display of the specified bitmap. The pixel is rendered in the foreground color of the GrafCon structure. It is rendered on the column and row specified by the x and y arguments respectively.
The call returns 0 if successful or an error code (a negative value) if an error occurs.
GRAFERR_COORDRANGE is returned if the specified location is outside the bitmap boundaries.
The current implementation of this routine is very slow. This will change in future releases.
Folio call implemented in Graphics folio V20.
