Revert "[ft] Fix memory bug in copying bitmaps"

This reverts commit a0f556f37fb7016aa304b7cf0e811c0d38f0b969.

The change was clearly wrong now that I read.  I was probably
tricked by what was fixed in the follow-up commit
e738079302a968b7b1fb9101cd4d92a8887bedce.

clip: Fix handling of special all-clipped cairo_clip_t

_cairo_clip_intersect_box() wasn't checking if it was called with the special,
read-only all-clipped clip and thus could have ended up writing to read-only
memory.

doc: Add missing sections and symbols for public docs

This adds a number of items to the documentation for which code docs
exist, and also adds sections for cairo-skia and cairo-surface-observer.

doc: Drop a couple quartz routines which distcheck claims don't exist

These routines actually do exist in the source code, and have proper
documentation, so I'm not sure why distcheck dislikes them, but it's
happier without these listed.

Fix warnings from check-doc-syntax.sh

$ ./check-doc-syntax.sh
Checking documentation for incorrect syntax
./cairo-types-private.h (148): WARNING: cairo_hash_entry_t: missing 'Since' field (is it a private type?)
./cairo-types-private.h (161): WARNING: cairo_hash_entry_t: not found
./cairo-types-private.h (175): WARNING: cairo_lcd_filter_t: missing 'Since' field (is it a private type?)

./cairo-region.c (857): WARNING: cairo_region_overlap_t: not found
./cairo-raster-source-pattern.c (62): WARNING: SECTION:cairo-raster-source 'Since' field in non-public element

The warnings about missing 'Since' fields are fixed by changing the
documentation comment so that the script can see that these are private types.

The documentation for cairo_region_overlap_t gets moved to cairo.h, just like
e.g. the documentation for cairo_status_t.

The 'Since' field from the SECTION:cairo-raster-source is removed, because this
kind of field is needed on the individual functions and structs, not on the
section.

Thanks to Bryce Harrington for bringing this up!

mask compositor: Set a check_composite method

Commit 503b6b9e2ea6 added a check_composite method to the mask compositor, but
only added it to one of the existing implementations. This commit fixes that.

In cairo-image-compositor.c, there is already a check_composite method which
just returns success for the traps compositor. This commit makes the mask
compositor use that one.

I don't want to say much about cairo-image-mask-compositor.c except that I
wondered why this file and the file above both define a non-static function
called _cairo_image_mask_compositor_get(). In my opinion, that file should just
be deleted, since it confuses e.g. ctags, but I'll let someone else clean this
up.

Fixes 493 crashes in the test suite for the test-mask target.

mesh-rasterize: Fix number of iterations

Commit 44a09f462c fixed a compiler warning, but changed the result of this code.
This is because the old 'for' loop did one more iteration than the new 'while'
loop. Fix this by incrementing the loop counter once before the loop.

Fixes: mesh-pattern mesh-pattern-accuracy mesh-pattern-conical
mesh-pattern-control-points mesh-pattern-fold mesh-pattern-overlap
mesh-pattern-transformed record-mesh
