caaa6764fa image: re-organize draw.go. 
There are no behavioral changes, only some copy-and-pastes.

Before, drawFillOver was next to drawCopyOver.

After, drawFillOver is next to drawFillSrc, which is more similar to
drawFillOver than drawCopyOver is.

Similarly, drawCopyOver is now next to drawCopySrc, etc.

1722ec22cd cgi: close stdout reader pipe when finished 
This causes the child, if still writing, to get an error or
SIGPIPE and most likely exit so our subsequent wait can
finish.

A more guaranteed fix would be putting a time limit on the
child's overall execution, but this fixes the problem
I was having.

Fixes #2059
