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).

Mozilla bug #475092

26999e5aa8 [region] Add cairo_region_intersect_rectangle() and _subtract_rectangle() 
Intersecting with and subtracting rectangles is quite common, and we
already have cairo_union_rectangle().

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
simplified significantly by calling cairo_region_union_rect()
repeatedly instead.

definitions that had it.

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

c88321d0a2 [region] Miscellaneous bug fixes. 
- Initialize region->status in _cairo_region_create_boxes()
- Make _cairo_region_copy() actually return a region.
- Fix a bug where a NULL region could be dereferenced

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

c2c637cf1d Simplify _cairo_clip_intersect_region() 
The intermediate intersection region is not necessary because if the
operation fails, clip->region will end up as a pixman error region.
