error.

edce97a750 [pdf] Remove false assertion. 
The stream itself may be in an error state, so an error could be raised.

b580a4a8d6 [test] Improve fault injection coverage 
In order to exercise the meta-surfaces, we need to inject faults into
cairo_surface_finish().

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).

aee71e2063 [test] Memfault checks. 
Don't assume an error means the test failed, check for injected allocation
errors.

979337dd4d [gl] Wire blend factors using dst alpha to constants for CAIRO_CONTENT_COLOR. 
This fixes the operator and operator-alpha tests to rgb24 destinations.
While we request an RGB texture, the returned texture has alpha bits, so when
we blend against it as a renderbuffer, we get the junk alpha values.  Whether
or not this is a driver bug, we'll have this problem when we get visuals
with alpha bits for windows despite not requestiong alpha, so we have to
handle it in cairo.

809f7dc4c8 [gl] Make sure test visuals for CAIRO_CONTENT_COLOR_ALPHA have alpha bits. 
Since we're just making FBOs, the visual chosen probably shouldn't matter,
and it doesn't on Intel.  But it does seem like the right thing to do.

26999e5aa8 [region] Add cairo_region_intersect_rectangle() and _subtract_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.
