exp/draw fast path for glyph images. · d7a6d228

Nigel Tao authored May 10, 2010

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.

big: cleanups and performance tuning · 52cc0581

Robert Griesemer authored May 08, 2010

- removed last argument (n) from all core arithmetic routines;
  instead, use the length of the result

- simplified nat.make implementation and chose a better capacity
  for new values, removed a TODO in the process

pidigits -s -n 10000 by ~9% (on a 3.06GHz Intel Core 2 Duo):
