1496c5cf51 [analysis] Use _cairo_region_init() 
Avoid secondary allocations of the thin region wrappers during surface
creation by embedding them into the parent structure. This has the
satisfactory side-effect of not requiring status checks which current code
lacks.

ad83765a14 [xlib] Allocate bounded region on stack. 
Eliminate the extremely short-lived and oft unnecessary heap allocation
of the region by first checking to see whether the clip exceeds the
surface bounds and only then intersect the clip with a local
stack-allocated region.

75b06b8bdb [pattern] Do not modify outparam on error path. 
The pdf backend was crashing as a failed pattern copy stored an invalid
pointer with the resource group.

f12d52bfca [test] Use xmalloc() to evade memfault. 
Do not use the simple malloc() as memfault will inject allocation failures
(unlike xmalloc() for which faults are excluded) - as this is unnecessary
inside the test harness and thus does not exercise any cairo code paths.

ca501d99bb [test] Disable signal handling under valgrind 
Capturing and handling the signals prevents valgrind from providing
backtraces for fatal signals -- which is often more useful.

f853972636 [win32] Fix building with libpng and zlib 
Include zlib and libpng dependencies using something like '$(cairo_dir)/../zlib/zdll.lib'
instead of just 'zdll.lib'. Also, do similarly for the headers.

9b496af5c2 Fix buffer size check in TrueType subsetting 
Andrew Cowie reported a problem with the Charis SIL font being
embedded as a fallback font.

The buffer size check for composite glyphs was incorrect causing the
subsetting to fail for some fonts.

8362c6f726 [type1] Fixup error path during write_charstrings() 
On the common error path we attempted to unlock a mutex that was not
always held, so reorder the error paths appropriately.

b0689f5611 Check for errors during get_mime_data() 
cairo_surface_get_mime_data() may raise an error on the surface, so we
need to check lest it goes unnoticed and we generate a corrupt file.

77ee65fd03 [win32] Fix horizontal glyph positioning bug 
The _cairo_win32_scaled_font_backend version of show_glyphs collects
glyph runs to hand to ExtTextOutW until the y-offset changes, then flushes the
glyphs buffered so far. As each glyph is buffered, it also calculates and
buffers the dx value for the preceding glyph.

However, when it sees a change in dy and decides to flush, it should *not*
append an entry to the dx buffer, as this would be the "dx" of the previous
glyph, and instead the new start_x value will be used for the new glyph run
that's being collected. This bug means that after any vertically-offset glyph,
the remaining glyphs in the run will get incorrect dx values (horizontal
escapement).

4b3245481c [region] Expand rect to rectangle in a couple of names 
Specifically,

	cairo_region_union_rect  ->  cairo_region_union_rectangle
	cairo_region_create_rect ->  cairo_region_create_rectangle

Also delete cairo_region_clear() which is not that useful.

bf6d9bc175 [region] Delete cairo_region_create_rectangles() 
It was only used in _cairo_traps_extract_region() which could be

ebd0e685ae [region] Consistently use rectangles in the API of regions 
Usually, rectangles are more useful than boxes, so regions should only
expose rectangles in their public API.

Specifically,
  _cairo_region_num_boxes becomes _cairo_region_num_rectangles
  _cairo_region_get_box becomes _cairo_region_get_rectangle

Remove the cairo_box_int_t type

Also add an assertion that the result of cairo_region_copy() is never
NULL.
