Merge branch 'device-offset-history' into cairo
diff-tree a6b1b014bbd12be0f20c44d38d8847181be6d3ae (from 40b39dddf9cd919fb2f456a8e296a60cc8296fbf)

Implement the device_offset functionality at surface, not gstate layer
This is a mega-patch that has the advantage that the entire test suite
passes both immediately before and immediately after this commit.
The disadvantage of the mega-patch is that it does not reflect the
development history of the device-offset branch, (with its various
fumblings and flailings). To capture that history, we will next merge
in that branch.

This fixes the self-copy test which was the last one that was really
failing due to device offsets.

Rip out device_{x,y}_scale.
This device scale stuff is currently not being used. However it is also adding
complexity to the current device-offset rework. And since it's not being tested
I'm sure we're getting it wrong. It's better to not even have it here rather
than having it be broken.

Move device offsets handling into high-level operations only (stroke/fill/paint/etc)
Remove all device offsets handling from internal cairo_surface methods,
which will become truly internal shortly. Have all device offsets
handled by top-level entry points (stroke/fill/paint/show_glyphs/mask, and
clipping).

Fix bug in test suite causing PS and PDF to fail with rgb24 and device offsets.
Patch from cworth at cworth.org.
The trick with this one is that the test suite is using device offsets
in a rather fabricated way, and the final copy from an offset surface
to a non-offset surface is between two surfaces of the same size, so
must be 1:1. To get this we turn the device offset off before the
copy.
In a more conventional use of device offsets the surfaces would be of
different sizes, and the offset would be desired during the copy.

Take device offsets into account when compositing scaled glyph images
Scaled glyph image surfaces have device offsets set on them to indicate
the location of the glyph origin; however, those offsets weren't being
taken into account for the call to composite, so the glyphs were
being doubly-offset by this amount.

Implement device offset/scale at cairo-surface layer
This patch implements device offset/scale at the cairo-surface layer,
instead of them just being multiplied into the CTM at operation time.
This allows identical drawing operations/clips/paths/etc. to operate
identically on a surface with or without a device offset (and still
have things end up in the same place relative to the dev offset).

Shrink the size of a couple of tests (and update reference images).
Shrink linear-gradient and text-pattern test outuput.
The real motivation for this is to hide an annoying difference in the
gradient output that occurs when under the influence of a device
offsets. My opinion is that the gradient output should not change due
to just an integer offset, but we currently don't have a precise
gradient specification, so this minor deviation really isn't relevant.
A better fix for this might have been to make the test suite more
forgiving of tiny differences, (perhaps on a per-test basis), but
another advantage of shrinking these tests is that they now run a lot
faster.
It is true that these tests now also exercise fewer different output
values, but that's not the designed purpose of the tests so I don't
feel bad about losing that characteristic.

Augment test framework to test everything under device offsets as well.
[With this change, two tests with gradients exhibit subtle differences
under device offsets. I don't think we actually care about them
though. -cworth]
