From: Søren Sandmann Pedersen <[email protected]>
glyph-test would sometimes set a solid image as an alpha map, which is
not allowed. When this happened and the debug spew was enabled,
messages like this one would be generated:
*** BUG ***
In pixman_image_set_alpha_map: The expression
!alpha_map || alpha_map->type == BITS was false
Set a breakpoint on '_pixman_log_error' to debug
Fix this by not passing the ALLOW_SOLID flag to create_image() when
the resulting is to be used as an alpha map.
