The values of globalCompositeOperation are very poorly defined:

Some math is probably needed; prose alone seems unlikely to be
sufficient.
I made a quick test at:
http://dbaron.org/tests/canvas/composite-operations
There are a number of tests for globalCompositeOperation here:

These tests are written pretty much to the letter of the specification,
but it would be appreciated if someone tried to verify the tests.
