The 5 additional bugs that will be shipped with 1.4 are
ft-text-vertical-layout-type1
radial-gradient
surface-pattern
surface-pattern-scale-down
surface-pattern-scale-up
Most of these are non-issues, (unbundled font for
ft-text-vertical-layout-type1), or very minor issues (radial-gradient
and surface-pattern). The only things in here that look like a real
bug are the surface-pattern-scale-down and surface-pattern-scale-up
tests where the xlib backend results have some non-1.0 alpha that is
very unexpected.
Embarrassingly enough, the test suite previously never called
into cairo_pattern_create_radial at all. Unsurprisingly, this
has led to bugs creeping into the radial gradient implementation.
