[cp-patches] Pixmap scaling patch

[Craig Black]

Hello,
The attached patch adds support for scaling pixmaps as used in two of the
Graphics.drawImage methods. Currently those methods throw
RuntimeExceptions when using offscreen images. I've also attached a simple
test that scales and flips a simple image. Let me know if it looks okay to
commit.

Thanks,
Craig
