Shorter and more in line with our general igt_ prefix for everything which isn't somehow intel or i915-gem or otherwise hw specific - these helpers here are all fully generic framebuffer handling functions based on kms + cairo. Well, the actual buffer alloc is done with i915 gem, but meh ;-) Two special cases: - bpp_depth_to_drm_format and drm_format_to_bpp completely lacked prefixes, so just add igt_. - write_fb was a bit misleading given that we have gem_write for uploading to buffers. Rename that to write_fb_to_png to make it crystal clear what this thing does even without looking at docs. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
