This splits out the cogl_path_ api into a separate cogl-path sub-library
like cogl-pango and cogl-gst. This enables developers to build Cogl with
this sub-library disabled if they don't need it which can be useful when
its important to keep the size of an application and its dependencies
down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path
have been renamed to cogl_path_{fill,stroke}.
There were a few places in core cogl and cogl-gst that referenced the
CoglPath api and these have been decoupled by using the CoglPrimitive
api instead. In the case of cogl_framebuffer_push_path_clip() the core
clip stack no longer accepts path clips directly but it's now possible
to get a CoglPrimitive for the fill of a path and so the implementation
of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as
a shim that first gets a CoglPrimitive and uses
cogl_framebuffer_push_primitive_clip instead.
We may want to consider renaming cogl_framebuffer_push_path_clip to
put it in the cogl_path_ namespace.

(cherry picked from commit 8aadfd829239534fb4ec8255cdea813d698c5a3f)
So as to avoid breaking the 1.x API or even the ABI since we are quite
late in the 1.16 development cycle the patch was modified to build
cogl-path as a noinst_LTLIBRARY before building cogl and link the code
directly into libcogl.so as it was previously. This way we can wait
until the start of the 1.18 cycle before splitting the code into a
separate libcogl-path.so.
This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid
breaking the 1.x API/ABI.

|
|
* @short_description: Functions for constructing and drawing 2D paths.
|
|
*
|
|
* There are two levels on which drawing with cogl-paths can be used.
|
|
* The highest level functions construct various simple primitive
|
|
* shapes to be either filled or stroked. Using a lower-level set of
|
|
* functions more complex and arbitrary paths can be constructed by
|
|
* concatenating straight line, bezier curve and arc segments.
|
|
*
|
|
* When constructing arbitrary paths, the current pen location is
|
|
* initialized using the move_to command. The subsequent path segments
|
|
* implicitly use the last pen location as their first vertex and move
|
|
* the pen location to the last vertex they produce at the end. Also
|
|
* there are special versions of functions that allow specifying the
|
|
* vertices of the path segments relative to the last pen location
|
|
* rather then in the absolute coordinates.
