 Libraries:
 
 - fix the problems in atari target, and flesh out its libraries.
+- c128 target: make syslib more complete (missing kernal routines)?
 - c64: make the graphics.BITMAP_ADDRESS configurable (VIC banking)
 - optimize several inner loops in gfx2 even further?
 - add modes 3 and perhaps even 2 to gfx2 (lores 16 color and 4 color)?
