/* This test framework allows limited testing of rendering results. Things are rendered, shown on
|
|||
|
* the framebuffer, read back from there and compared to expected colors.
|
|||
|
*
|
|||
|
* However, neither d3d nor opengl is guaranted to be pixel exact, and thus the capability of this test
|
|||
|
* is rather limited. As a general guideline for adding tests, do not rely on corner pixels. Draw a big enought
|
|||
|
* area which shows specific behavior(like a quad on the whole screen), and try to get resulting colos with
|
|||
|
* all bits set or unset in all channels(like pure red, green, blue, white, black). Hopefully everything that
|
|||
|
* causes visible results in games can be tested in a way that does not depend on pixel exactness
