From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>
For all those IGT tests that need an easy way to draw rectangles on
buffers using different methods. Current planned users: FBC and PSR
CRC tests.
There is also a tests/kms_draw_crc program to check if the library is
sane.
v2: - Move the test from lib/tests to tests/ (Daniel).
- Add igt_require() to filter out the swizzling/tiling methods we
don't support (Daniel).
- Simplify reloc handling on the BLT case (Daniel).
- Document enum igt_draw_method (Daniel).
- Document igt_draw_get_method_name() (Paulo).
v3: - Add IGT_DRAW_MMAP_WC (Chris).
- Implement the other trivial swizzling methods (Chris).
- Remove the gem_sync() calls (Chris).
