[webkit-dev] Using ref tests for repaint bugs

As Simon states, some repaint tests will likely not be possible to write
correctly as ref tests, but some of them I think they fit very well in the
happy-no-pixel-test bucket :). If people decide it's a direction worth
investigating, I'll give the idea a spin.

Don't the pixel tests face the same kind of risk, of a subsequent paint
masking the repaint bug? Preserving this risk, but reducing the maintenance
cost for the test is still an important improvement.
