* clutter/clutter-feature.c: No need to call clutter_feature_init()
each time: it's private and should never be seen from the outside;
add a warning, just in case something screws up and calls it more
than once.
* clutter/clutter-private.h: Move clutter_feature_init()
declaration here: you shouldn't even need to initialise
features yourself.
* clutter/clutter-feature.c: call clutter_feature_init()
each time you try to access the feature list; add a static
lock around the feature flags container; add api documentation.
* clutter/clutter-feature.h: Add a type for the feature flags
to make bindings happy.
* clutter/Makefile.am:
* clutter/clutter-feature.c:
* clutter/clutter-feature.h:
Add new funcs for checking for available runtime GL
extensions.
* clutter/clutter-clone-texture.c:
* clutter/clutter-texture.c:
Add support for non power of two textures
if GL_TEXTURE_RECTANGLE_ARB extension available ( at runtime ).
Should lower texture memory needs a little.
