This adds a conformance test which renders a rectangle texture using the two wrap modes clamp-to-edge and repeat. It then verifies that the correct region of the texture is drawn for the texture coordinates that are > 1.0. The test currently always fails. The cogl_framebuffer_draw_rectangle function is documented to always take normalized texture coordinates regardless of the coordinate system of the texture. This works correctly if all of the texture coordinates are in the range [0.0,1.0] because cogl-primitives uses a different code path in that case. However if the multiple-quad code path is taken then the coordinates actually need to un-normalized for it to work. There is a comment in cogl_meta_texture_foreach_in_region() which implies that the incoming coordinates should always be normalized. The documentation for the callback says that the resulting sub-texture coordinates will always be in the coordinate system of the low-level texture. However it doesn't work out like this because the meta texture function uses the span iterating function which always returns normalized coordinates. It looks like there needs to be some more conversions going on somewhere. Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit d2059bb32b8015060e10f41dbbb68d4230b47ddb) |
