* clutter/clutter-behaviour-path.c: Reverse the list of
parsed knots, to preserve the real ordering after prepending
them (thanks to Øyvind for spotting this).
* clutter/clutter-behaviour-bspline.c: Ditto as above.
Most of these fixes are simple symbol shadowing issues, like index and the
braindead y0 and y1 extern symbols exported by math.h on GNU libc systems.
There is a masking issue in ClutterTexture which should be checked; I ran
the tests and everything looked fine.
The rest are just unused variables.
* clutter/clutter-behaviour-bspline.c: Kill off some deep pointer
indirections; use CLUTTER_NOTE() instead of ifdeffed out g_debug();
add checks in every public entry point; move some initialisations
of private data structures out of the constructor and into the
init function, where they belong.
