I'd personally try something horribly inefficient but easier for me to 
understand like this, until GPU memory is filled or CPU->GPU memory 
bandwidth runs out, at which point I'd use the minimum number of 
rectangles that fill the screen and draw only those images:

[gemhead]

[t a b]/[0(
  |       :
[repeat 12]       << from zexy, or use [gemlist] and [until]
  |       :
[t a b]/[f]X[+1]
  |       :\
[pix_multiimage]
  |       :
  |      [pd index to coordinates etc]
  |       |
[translate]
  |
[rectangle]
