[Bug awt/29510] BufferedImage / Graphics2D performance problem

I see this too, but only when using the INT_RGB image type (try changing it to
INT_ARGB, and the speed will pick up again).

Looks like INT_RGB uses 24 bits in its ColorModel, while the
BufferedImageGraphics looks for a 32-bit ColorModel when checking for fast-copy
compatibility.  The change in BufferedImage came from Sven back in August, part
of his half-finished overhaul.

I'll write some mauve tests later to check whether it should indeed be 24-bit
or 32-bit, and change either the BufferedImage or BufferedImageGraphics to
match it.
