This is a step toward allowing device scaling in addition to device offsets.
So far, the scale values are still always 1.0 so only the translation is
actually being used. But most of the code is in place for doing scaling as
well and it just needs to be hooked up.
There are some fragile parts in this code, all of which involve using the
translation without the scale, (so grep for device_transform.x0 or
device_transform->x0). Some of these are likely bugs that will hopefully
be obvious once we start using the scale. Others are OK if only because
we 'know' that we aren't ever setting device scaling on a surface that
has a device offset (we only set device scaling on surfaces we create
internally and we don't export device scaling to the user).
All of these fragile parts in the code have been marked with comments of
the form: XXX: FRAGILE.
This patch was produced by running git-stripspace on all *.[ch] files
within cairo. Note that this script would have also created all the changes
from the previous commits to remove trailing whitespace.

Throw away old gradient code from within cairo-pattern.c in favor of using new support in pixman for gradients.
Update reference images for all tests involving gradients since the gradient output has changed slightly.

Also, eliminate all support for compiling against, or running with old, deprecated names for functions.
Deal with all of the removals.
Add new function to return current matrix: cairo_get_matrix
Deprecate the following functions (in documentation): cairo_matrix_create cairo_matrix_destroy cairo_matrix_get_affine
Rename: cairo_matrix_set_affine -> cairo_matrix_init cairo_matrix_set_identity -> cairo_matrix_init_identity
Add other new matrix initialization functions: cairo_matrix_init_translate cairo_matrix_init_scale cairo_matrix_init_rotate
Change return type of almost all cairo_matrix functions from cairo_status_t to void.
Track changes to cairo_matrix_t interface.
Add a test case showing the same path drawn under various transforms, (including skews set directly by initializing a cairo_matrix_t).

src/cairo.[ch] src/cairo-matrix.c: Add some inline docs for arcs and matrices.
gtk-doc.m4 acinclude.m4: Check in files from gtk-doc to make the dependency on gtk-doc optional.
Add --enable-gtk-doc to the default args.
Remove cache memory usage assertions as single objects can be larger than the cache size
Decompose font matrix transformations into a couple of helper routines. Return all metrics in font space.
Eliminate compiler warning
Expect glyph metrics to be in font space. Compute text extents by fetching one glyph metric at a time, transforming to user space and computing the overall bounding box.
use 'sincos' where available. Scale factors now ensure the non-scale transform is area preserving. Scale factors requires another parameter to mark the fixed axis.
Change license to LGPL Mark int32x32_64_mul as broken (which it still is)
Ensure each glyph is located as close to the specified position as possible
interface change to _cairo_matrix_compute_scale_factors
Check for slim.
Include slim_{export,import}.h as needed; mark all symbols __external_linkage.
Include slim_internal.h; mark all symbols __internal_linkage. Provide slim_hidden_proto symbols as needed.
Provide slim_hidden_def symbols as needed.
Mark static. (cairo_traps_add_trap_from_points): Likewise.
