b0283611e4 fix issue 798
cannot allocate an audomatic temp
while real registers are allocated.
there is a chance that the automatic
will be allocated to one of the
allocated registers. the fix is to
not registerize such variables.

efda3aba10 Fast-ish path for drawing onto an image.RGBA destination.
Time to draw.Draw a 200x200 image fell from 18.4ms (and 1 malloc) to
5.6ms (and 0 mallocs). It's still relatively slow since it assumes
nothing about the src or mask images, but it does remove the malloc.
There are existing faster, more specialized paths for copies, fills
and image glyph masks.

Also added a "compare to a slow but obviously correct implementation"
check to draw_test.go.

d7a6d22852 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.
