Seems like this should be added to the conformance tests.

Er, a FLOAT+RGB canvas at 1024x1024 is 12MiB.
You seem to be relying on context2d.createImageData(1024, 1024) to create your buffer, which only allocates 4MiB, since it assumes it's dealing with a 32bbp canvas of size 1024x1024.
Are you sure this should not be an error in Chrome?

Removing webgl-test-needed as this is a dupe of another webgl-test-needed bug.
