Please split the various separate changes in different patches.

The i-g-t tag should also appear in the subject prefix rather than the
subject tag. (i.e. use --subject-prefix="PATCH i-g-t" or git config
format.subjectprefix "PATCH i-g-t").

Other cairo functions use int rather than uint16_t for width and
height, so int should be sufficient here too, at least for
consistency.

cairo is already included via igt_kms.h and igt_fb.h.

What is the purpose of the new filename parameter? It always appears
to be set to to the same value (FILE_NAME) as used previously in the
vall to igt_paint_image.
