From: Sagar Kamble <sagar.a.kamble@intel.com>

v1: Added 128x128 and 256x256 cursor size support.

v2: Refined the test to use igt_subtest_f and automate enumeration.

v3: Restructuring test enumeration using drmGetCap. [Daniel's review comments]

Nitpick: indent error, also the same on some of the following lines.

I would add here an explicit assert about the above. Other than this and
the formatting issue above it looks ok:
