76b871d710 [cairo-image-surface] Remove status return for hard-coded CAIRO_STATUS_SUCCESS. 
Remove the status return if the function can only return
CAIRO_STATUS_SUCCESS, and remove the then surplus conditionals.

4e39e30d83 [cairo-pen] Remove status from _cairo_pen_find_active_vertex_*() 
This pair of functions unconditionally return SUCCESS, so remove the
status return and supporting tests from their callers.

b72b06cc22 [cairo-pen] Remove hard-coded CAIRO_STATUS_SUCCESS from _stroke_spline_half()

_cairo_pen_stroke_spline_half() unconditionally returned SUCCESS.

e24969a94a [cairo-pdf-surface] cairo_pattern_set_matrix guarantees invertibility. 
Be consistent in asserting that the pattern matrix is inverted
successfully and remove a couple of redundant checks.

50ebdda3a9 [cairo-pattern] Assert that the pattern->matrix is invertible. 
We guarantee when setting the pattern->matrix that it is invertible, so
merely assert that it is so when we attempt to use its inverse.

dereferencing said format doesn't work as intended.

bc635da45a [cairo-ft-font] Decrement lock count on error. 
As noted in http://bugs.freedesktop.org/show_bug.cgi?id=12026 the error
path of _cairo_ft_unscaled_font_lock_face() failed to reset the
unscaled->lock_count before releasing the mutex and returning NULL.

35ef8419a9 [cairo-matrix] Check determinant for invalid numbers. 
By checking matrices for invalid determinants, we can prevent the
setting and application of invalid matrices.

The trick used here is that NaNs, as specified by IEE754, always
return FALSE in comparisons. Since we know that the square of the
determinant must be positive definite, then if the comparison is
FALSE the computation must have resulted in a NaN.

5c7d2d14d7 [fix] Avoid int overflow when allocating large buffers 
This patch introduces three macros: _cairo_malloc_ab,
_cairo_malloc_abc, _cairo_malloc_ab_plus_c and replaces various calls
to malloc(a*b), malloc(a*b*c), and malloc(a*b+c) with them.  The macros
return NULL if int overflow would occur during the allocation.  See
CODING_STYLE for more information.

2bf3e31da9 Prefer local dpy variable instead of display->display 
This was a tiny piece of cleanup that had been erroneously included
with some earlier functional changes, (so it went through a cycle
of being applied and reverted). It's back now in its own commit.

eebb0df512 Revert "[cairo-xlib-display] Hide XErrors during processing of the work queue." 
This reverts commit 285b702ef6.

The recent commit of 0791f342b9 fixes
the same bug that 285b702e was fixing, but without introducing any
performance-killing calls to XSync. So we can drop those now.

b019cb8a7a Revert "[cairo-xlib-surface] Check for errors before installing a NOOP error handler." 
This reverts commit 7016614dd9.

We want to avoid any negative performance impacts due to extra calls
to XSync. The fact that X errors can be missed with this appraoch is
undesirable of course---a proper fix will likely involve moving to
XCB which will hopefully allow us to do the error-checking the way
we want without any performance penalty.

0791f342b9 Avoid deferring resource cleanup for application drawables 
This eliminates X errors propagated from cairo due to cleaning up
Render Pictures after the application had already destroyed the
Drawable they reference. (It would be nice if the X server wouldn't
complain that some cleanup work is already done, but there you
have it.)

This fix has been verified to fix the bug causing OpenOffice.org to
crash as described here:

	XError on right click menus in OOo.
	https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=243811

And unlike other proposed fixes for this bug, this fix does not
introduce any new calls to XSync, (and thereby avoids performance
concerns from those).
