cogl: Remove CoglBool, use gboolean instead
This basically reverts commit 54735dec, which tried to avoid the GLib-defined types in favor the standard C ones. One exception to this is the bool type, for which the commit introduces a new type CoglBool.
Let's just get rid of this type in favor of having consistency with the
GLib types. Note by the way that neither CoglBool nor gboolean (which
has a size of int
) are completely compatible with bool (size char
).
