[PATCH 1/8] glamor: glamor_poly_point_nf cannot fail for non-DDX pixmaps

[Keith Packard]

All of the glamor _nf functions must check to see if the DDX can
access the pixmap directly before returning failure back to the
driver; this restructures the point code to split out the _nf checking
from the _gl code.
