exp/draw fast path for glyph images.
To draw.Draw a 32x32 image.Alpha 10000 times,
Before: 633ms with 10000 mallocs
After: 49ms with 0 mallocs
These times are just blitting an image.Alpha, and do not include
rasterizing a glyph's vector contours to an image.Alpha.
The "generic" test case in draw_test.go tests this fast path.
