[Piglit] [PATCH] Add test case to verify large textures are handled correctly in mesa

Sat Mar 17 22:38:53 PDT 2012
This test tries to create the maximum supported texture using
gltexImage1D/2D/3D functions and later modifies it using
glTexSubImage1D/2D/3D functions.
At the moment Intel driver throws GL_OUT_OF_MEMORY and an assertion
failure / a SIGBUS with large textures.
Test reproduces the errors reported in:
https://bugs.freedesktop.org/show_bug.cgi?id=44970
https://bugs.freedesktop.org/show_bug.cgi?id=46303
V2: Added the test using proxy textures, deleted redundant code,
data array allocation based on size returned
V3: Continue testing with other formats if ARB_texture_float is not present.
Moved the test case to tests/texturing with an appropriate name.
Removed the loop which was testing with a number of large textures.
Added GL_OUT_OF_MEMORY as an expected error.
Added GL_TEXTURE_RECTANGLE in texture target array.
V4: Removed redundant code.

+ * Verify that large textures are handled properly in mesa driver.
+ *
+ * This test works by calling glTexImage1D/2D/3D and glTexSubImage1D/2D/3D
+ * functions with different texture targets. Each texture target is tested
+ * with maximum supported texture size.
+ * All the calls to glTexImage2D() and glTexSubImage2D() should ensure no
+ * segmentation fault / assertion failure in mesa driver.
+ *
+ * This test case reproduces the errors reported in:
+ * 1. https://bugs.freedesktop.org/show_bug.cgi?id=44970
+ * Use GL_TEXTURE_2D and GL_RGBA16
+ *
+ * 2. https://bugs.freedesktop.org/show_bug.cgi?id=46303
+ *
+ * GL_OUT_OF_MEMORY is an expected GL error in this tesyt case.
