[Intel-gfx] [PATCH i-g-t 1/3] lib/igt_fb: Allow specifiying object tiling when creating frame buffers

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Currently object tiling is inferred from the frame buffer modifier
and only for legacy X scanout.

It is useful to support overriding this selection for certain tests
so add the capability.
