Prior to this change, cogl often queried GLX so that it returned
a framebuffer that could not support an alpha component.

In order to be more consistent with backends such as gl, support for
creating a surface from content, width, and height parameters was
moved into the backend itself. The option to pass cairo-cogl a
framebuffer to create a texture from still exists, just now it is
not the only option.

This makes it so that operators requiring transparent values to be
used outside of the bounds of the source and/or mask textures will
trigger a second rendering of transparent pixels.

This adds correct support for negative stride images by uploading
them to a texture in their upside-down orientation and then
vertically inverting the matrix with which they are read, which
is required because OpenGL (and therefore cogl) cannot pack pixels
with a negative stride.

Prior to this change, API functions like path_exents returned
incorrect results if the cogl-specific representation of rectangular
paths was being used.

Prior to this, the rectangular filling fast path passed arguments to
_cairo_cogl_journal_log_rectangle as if they represented the
coordinates of two opposite points on the rectangle, when the arguments
actually represent a rectangle with the x and y coordinates of one
point and the width and height of the rectangle.

Prior to this change, the boilerplate code crashed when given surface
dimensions less than 1. This fixes such behaviour by rounding the
dimensions up to 1, which is also done by the boilerplate code for
several other backends.

Many of the tests in the test suite do many replays of different
small parts of a single surface. When combined with the cogl backend's
journaling mechanism, this consumes very large amounts of memory, as
the entire surface is allocated for each replay. This changes this
behaviour so that only the portion of the surface that will be used
is allocated.

Prior to this change, the context functions were using the accelerated

This changes the interpretation of multiple boxes in the clip from
using the intersection of the multiple boxes to using the union of

Prior to this change, CAIRO_EXTEND_NONE was handled the same way as
CAIRO_EXTEND_PAD, which produced incorrect results in many tests.
This fixes such behaviour by created a per-source and per-mask clip
that is applied so that areas outside the bounds of the source or
mask textures are not sampled during drawing.

Cogl enters into an infinite recursion if a texture is specified
for layer 1 of a pipeline but no texture is specified for layer 0.
This works around the bug by setting the mask texture on layer 0
if there is no source texture.

The buffer stack was moved from the surface to the device, as
mapped buffers are shared across all surfaces using the device
and more than one surface may be doing so. Stemming from this, if
a surface tries to map a buffer without first unmapping one that
has been mapped by another surface, it will trigger an error.
The parent backend functions were moved from the device to the
context, as it is possible that the context creation function could
be passed a non-cogl device. Prior to this change, many of the
subsurface tests segfaulted.

Previously, if an unbounded recording surface was given as the
source, the program triggered an assertion failure in the recording
surface code, as acquire_source_image cannot be used on the surface
in this case. This adds a new path to deal with such an unbounded
source surface.

Update fontconfig wrap to upstream now that it's been merged.
Add gperf wrap which is needed for fontconfig, same as in the
upstream fontconfig repo (this can't be put into wrapdb yet
because it requires changes to source files).
- vsnprintf and snprintf are available since vs2015
- define ISREG if not provided
- guard unistd.h include with HAVE_UNISTD_H
- isnan() is available after vs2010
When the build dir is different from the source dir,
"png.png" is not a valid path. As we can't dispose of
an allocated filename, we add an atexit handler.
This way all binutils tools are detected with $CHOST prefix
if exist. And strings is allowed to be substituted with
STRINGS environment override, so 'llvm-strings' (or other)
alternative can be used.
