40b6d8842e Remove radial-gradient test from XFAIL list 
This test has not been failing since the fix in:

	772edc9133

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

e803e2e69b [cairo-pattern] Add a cache of two color stops to cairo_gradient_pattern_t 
Most of gradients have only two color stops.  This avoids
calling malloc() for those cases.

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 :).

1bd073a1a2 [cairo-path-fixed] Merge op and arg bufs 
This means, we have to malloc only one buffer, not two.  Worst case
is that one always draws curves, which fills the arg (point) buffer
six times faster than op buffer.  But that's not a big deal since
each op takes 1 byte, while each point takes 8 bytes.  So op space
is cheap to spare, so to speak (about 10% memory waste at worst).

5750d669af [cairo-path-fixed] Avoid malloc for small paths 
We do this by including an initial op and arg buf in cairo_path_fixed_t,
so for small paths we don't have to alloc those buffers.

The way this is done is a bit unusual.  Specifically, using an array of
length one instead of a normal member:

-    cairo_path_op_buf_t *op_buf_head;
+    cairo_path_op_buf_t  op_buf_head[1];

Has the advantage that read-only use of the buffers does not need any
change as arrays act like pointers syntactically.  All manipulation code
however needs to be updates, which the patch supposed does.  Still, there
seems to be bugs remaining as cairo-perf quits with a Bad X Request error
with this patch.

14cab8b020 Correct an off-by-one in the reflection of the convolution index. 
Currently the convolution code uses the formula 2*(N-1)-n to reflect the index
n when n is greater than or equal to N.
This is wrong as n=N -> 2*(N-1)-N = N-2 instead of N-1.

Furthermore when the image is small, e.g. at the highest levels of the
pyramid, this causes the code to index before the start of the array and
causes valgrind to issue a warning.

789aada06b Avoid the struct copy when source and destination are the same. 
On some architectures, gcc will emit a memcpy for structure copies which will
produce a valgrind warning when the source and destination pointers are the
same. Workaround this issue by explicitly checking the source and destination
for inequality before doing the structure assignment.
