[PATCH v2 0/5] Create tests for the drm_rect functions

[Arthur Grillo]

This patchset seeks to add unit tests for the rest of the functions on
the drm_rect.c.

The test coverage report generated by the gcov[1] tool states that this
set reaches 100% of coverage on the drm_rect.c file. This would be
very good for future development on the file.

Thanks for reviewing!

Best regards,
~Arthur Grillo

- Create parameterized tests for drm_rect_intersect().
- Use .16 binary fixed point values on the drm_rect_calc_hscale() and
  drm_rect_calc_vscale() tests.
- Replace INT_MIN for 0 on the on the drm_rect_calc_hscale() and
  drm_rect_calc_vscale() tests.
- Assign nonzero values to the width and height parameters of the
  drm_rect_rotate() and drm_rect_rotate_inv() tests.

  and drm_rect_rotate_inv() tests.
