Split test-point-sprite into two, one without checking orientation
There is currently a known bug where when rendering offscreen point
sprites will be rendered upside-down. For that reason
test-point-sprite is marked as a known failure because it checks the
orientation of the point sprites and the conformance test suite is
rendered to offscreen buffers by default. However this doesn't help to
catch more general failures that stop the point sprites being rendered
at all. To fix this the test-point-sprite test has been split into two
tests, one which verifies the orientation and one which does not. The
two tests are in the same source file and internally share the same
static function but pass a flag to specify whether to check the
orientation. If the orientation should be ignored then it will create
a 2x1 texture instead of a 2x2 texture so that it will appear the same
regardless of whether it is upside-down. The checks for the colors
have been altered accordingly.
