I would like to scroll text in the overlay planes, but rectcopy is misbehaving.
For instance, the following core dumps:
#include <gl.h>
main()
{
long winID;
prefsize(300, 200);
foreground();
winID = winopen("rectcopy");
clear();
drawmode(OVERDRAW);
mapcolor(1, 255, 255, 255);
color(1);
cmov2i(50, 50);
charstr("try me out for size");
rectcopy(50, 50, 200, 100, 10, 10); /* bombola! */
drawmode(NORMALDRAW);
pause();
}
Take out the 'drawmode(OVERDRAW);' and it works as expected.
By trial and error I've discovered that setting 'overlay(4)'
avoids a core dump, but produces strange results.
Could some kind soul show me the light? Thanks.

That's on a 4/320 VGX, with the multibuffer board.
