6ff2439b33 Implement _cairo_traps_tessellate_triangle with _cairo_traps_tessellate_convex_quad 
The newly rewritten convex_quad code is actually simpler than the
triangle code being replaced here. This also allows us to throw
away the problematic _compute_x function which can't handle
horizontal lines, (divide by zero). So the cairo world becomes a
better place.

53ae6ea957 Fix _cairo_traps_tessellate_convex_quad to handle a == b 
This case was found in an attempt to use the convex_quad function
for tessellating triangles as well. Fortunately the fix is very
easy.

96d8f58daf Clear the XRender data on display closure. 
Use the new hook functions to register a callback for xlib to clear
the private glyph data when the display is closed. In order to do this
we need to reset the glyph cache inside the generic scaled font as well.

ad7698feb5 Introduce hooks for _cairo_xlib_close_display() 
This patch adds a simple hook data type for a notifier style callback
and introduces two functions to manipulate a list of callbacks for
cleaning up on display closure.

3d3173d176 Add svg-specific reference image for radial-gradient test. 
This isn't strictly needed, (pdiff allows the test to pass without the
image), but it sure runs faster this way.

75201c12be check-def.sh: Adjust test to exempt _cairo_test_* functions as well as _cairo_*_test_* 
This test started failing with the recent renaming of the following
three functions, (before they had no cairo in their names so they
were not getting picked up at all):

_cairo_test_fallback_surface_create
_cairo_test_meta_surface_create
_cairo_test_paginated_surface_create_for_data

With this change, the failure now goes away again.

1f3a5b4e12 Fix bugs in _cairo_traps_tessellate_convex_quad 
The previous code was not handling all cases correctly, (yes,
even something as simple as a quadrilateral can exhibit a
remarkably large number of different cases when tessellation
is attempted).

This fix now introduces slope comparison which handles several
cases that were mis-handled with the previous implementation which
only used independent sorting of the X and Y values of the
coordinates.

This fixes the skew-extreme test case and the bug reported here:

	Skew transforms were broken by the cairo update in December

This test has not been failing since the fix in:

So get rid of the '1 unexpected passes' complaint.

a7595c1295 [Makefile.am] Do not distribute cairo-features.h, Ouch! 
We were accidentally doing that by not marking it noinst.
Moreover, no need to mark it as BUILD_SOURCES, since it's
created by configure, not make.

f3c8d82d6d [test] If backends are limited and all untested, pass the test 
This is necessary to ensure that limiting backends using
CAIRO_TEST_TARGET does not increase the number of tests failing,
which is a desirable invariant.

bc8987068d [cairo_t] Make path an array of size one 
This is more natural since cr->path can be used as if it was a pointer.
This means, for example, if we move on to making it a pointer, most of
the code using it does not need any change.  So we get some level of
encapsulation of implementation details, if you prefer the terminology :).
