Elizabeth Figura d3ba810c98 tests: Stop probing all pixels when drawing a uniform colour.
This is simply unnecessary and wastes time.

As part of this, simply remove the "all" directive. Only for a couple of tests
is it even potentially interesting to validate all pixels (e.g.
nointerpolation.shader_test), and for those "all" is replaced with an explicit
(0, 0, 640, 480) rect.

In all other cases we just probe (0, 0).
