Simple; do NOT use subroutine unless really, really necessary (such as
calling
the bankswitch function).
Do NOT use a single putpixel as your primitive. If you want to draw lines,
use
or create a routine which draws the whole line, NOT a routine that
calculates all
pixel co-ordinates and then invokes a putpixel routine.
Same story for rectangles, bars, circles, elipses, polygons,etc...
