Occlusion query stress tests
Tests:
+ dEQP-GLES3.stress.occlusion_query.*
Includes:
+ Uses primitives drawn with GL_TRIANGLES
+ Uses query target ANY_SAMPLES_PASSED
Excludes:
+ Occlusion query result verification based on framebuffer
Description:
Occlusion query stress tests generate large amounts of occlusion queries
in order to test implementation's ability to handle them. First a
specified number of occluding triangles are drawn. Then the occlusion
query is started, specified number of target triangles are drawn and the
occlusion query is terminated. After all occlusion queries and triangle
draws are executed, glFinish() is called and all query results are read.
Actual query result values are not verified - only trouble-free result
retrieval is tested. Query result correctness can be implemented later
by inspecting framebuffer contents.
