This avoids both function call overhead and extra checks for values that
are outside MININT/MAXINT range, for the uses inside GeglBuffer we only
care about coordinates that are representable as integers - thus these
inline-able shortcut versions are good enough for us.

The speedup seems to consistently make all samplers about 10% faster
according to the tests in perf/

Two gegl headers test for G_OS_WIN32, so have them include a glib header
proactively. Currently, in every case in gegl where these two are
included, a glib header had already been included. However, this is not
assured to be true later, given the possibility of code creep.

Also adds CMYK type model as a valid alternative to being linear in
buffer scale blitting algorithms.

This reverts earlier indentation breaking changes when GeglRectangle was
renamed GeglBufferRectangle this change also retains the existing released API
and ABI more exactly.

The 2x2 matrix is only used by GeglBuffer and its API, gimp-2.10 does not
use the symbols - we are remaining abi compatible but are rearranging
locations of symbols.

This avoids a couple of extra function calls, as well as avoids a switch per
scanline of tile which is a more significant saving.

Primary motivation being that we then get a higher number of
linux/OSX making it possible for more temporary allocations
inside buffer handling to avoid the function call overheads
of malloc/free.

Bringing back the performance lost when first moving to always rendering in
linear, we're now at about 80% of the scaled fetch speed for u8 buffers before
the linear correctness fix.

Adding a GEGL_MIPMAP_RENDERING environment variable, which when set causes
gegl_node_blit to pass this level, rather than 0 to the eval_manager for
rendering. The level argument is now propagated all the way down to the
operations process() vfuncs.

* Move enough of GeglOperation to gegl-types.h for introspection
to identify it.
* Move the private GeglPad and GeglConnection types to
gegl-types-internal.h.

Remove the GEGL_INTERNAL define and instead of having incompatible
public and internal APIs kept under control through preprocessing,
make the internals depend on the public API and use the strategy of
having a public API that is a subset of the internal API.

Add GeglConfig to the API as an opaque struct so that we don't need to
have different interfaces publicly and internally for gegl_config()

Rename gegl-types.h to gegl-types-internal.h so that we can have a
gegl-types.h that is public without any distracting preprocessor
directives.

* gegl/Makefile.am: added gegl-chant.h and module/geglmodule*.h to the
set of headers to be installed in the gegl header base dir.
* gegl/module/geglmodule.h: added comment about module ABI versions,
and updated instruction on when this ABI should be incremented. (we
should probably allow a range of ABIs, one to be incremented on ABI
addition and the lower threshold to be incremented on ABI change.
