0b5d44537b Allow the user to manually specify format modifiers 
* 12to11.conf (DRMFOURCCH): New variable.
* 12to11.man: Document new resource.
* Imakefile (GENHEADERS): Add
drm_modifiers.h.:(drm_modifiers.h): New target.
(cleandir): Clean up.
* compositor.h: Update prototypes.
* fns.c (TransformBox): Move to transform.c.
* frame_clock.c (PostEndFrame): Use 200 us, since 100 us is not
always enough.
* picture_renderer.c (struct _DrmModifierName): New structure.
(known_modifiers): New array.
(AddAdditionalModifier, ParseAdditionalModifiers)
(InitAdditionalModifiers): New functions.
(InitRenderFuncs): Call them.
(ApplyInverseTransform): Accept buffer width and height instead
of PictureBuffer.  Move to transform.c.
(MaybeApplyTransform): Adjust calls.
(FindSupportedModifiers, InitDrmFormats): Stop adding the linear
format by default, and let the user specify it instead.
* subcompositor.c (InvertTransform): Move to transform.c.
* svnignore.txt: Add new generated header.
* transform.c (ApplyInverseTransform, TransformBox)
(InvertTransform): Move some functions here as they will be used
in the EGL backend.
