19    Scissoring Tests

21Tests:
22 + dEQP-GLES2.functional.scissor.*
23 + dEQP-GLES3.functional.scissor.*
24
25Includes:
26 + Primitives
27   - Points
28   - Lines
29   - Triangles
30 + Clears (including GLES 3 only ones)
31 + Framebuffer blits (GLES 3)
32 + Scissor configurations
33   - Enclosing rendered area
34   - Enclosed by rendered area (if applicable)
35   - Partially containing rendered area
36   - (Partially) outside render target

39Excludes:
40 + Blits to/from multiple buffers
41 + Partially clipped points

43Description:
44
45This test set compares images rendered by the target with the scissor test
46enabled to references generated with the scissor test disabled but with
47areas outside the scissor rectangle cleared by the test logic.
48
49All primitive types are tested in all reasonable scissor configurations
50listed above. Points are tested in a somewhat limited fashion since
51support for point sizes above one is not required.
52
53After clearing with scissoring enabled, depth and stencil clears disable
54scissoring and render a colored fullscreen quad with depth & stencil
55tests requiring values set by the previous clears to produce the final output.
