Add a conformance test for point sprites This adds a conformance test which renders a texture point using a 2x2 texture with a different color for each texel. It then verifies that each texel is mapped to the correct position on the point. The test is currently failing. The test requires the point sprite feature flag so this patch also adds a TEST_REQUIREMENT_* flag for that. Reviewed-by: Robert Bragg <robert@linux.intel.com>

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

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.

Adds cogl_framebuffer_draw_[*_]rectangle functions This adds experimental 2.0 api replacements for the cogl_rectangle[_*] functions that don't depend on having a current pipeline set on the context via cogl_{set,push}_source() or having a current framebuffer set on the context via cogl_push_framebuffer(). The aim for 2.0 is to switch away from having a statefull context that affects drawing to having framebuffer drawing apis that are explicitly passed a framebuffer and pipeline. To test this change several of the conformance tests were updated to use this api instead of cogl_rectangle and cogl_rectangle_with_texture_coords.

The aim for 2.0 is to switch away from having a statefull context that affects drawing to having framebuffer drawing apis that are explicitly passed a framebuffer and pipeline. To test this change several of the conformance tests were updated to use this api instead of cogl_rectangle and cogl_rectangle_with_texture_coords. Since it's quite laborious going through all of the conformance tests the opportunity was taken to make other clean ups in the conformance tests to replace other uses of 1.x api with experimental 2.0 api so long as that didn't affect what was being tested.

Add a conformance test for point sprites This adds a conformance test which renders a texture point using a 2x2 texture with a different color for each texel. It then verifies that each texel is mapped to the correct position on the point. The test is currently failing. The test requires the point sprite feature flag so this patch also adds a TEST_REQUIREMENT_* flag for that. Reviewed-by: Robert Bragg <robert@linux.intel.com>

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. Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 51b7fdbe17f300cf2edf42c2ca740ad748c9fd78)

Adds cogl_framebuffer_draw_[*_]rectangle functions This adds experimental 2.0 api replacements for the cogl_rectangle[_*] functions that don't depend on having a current pipeline set on the context via cogl_{set,push}_source() or having a current framebuffer set on the context via cogl_push_framebuffer().
