Glimpse 3.0.0 updates Glimpse to OpenGL 3.0, removing all usage of deprecated OpenGL 2.0 fixed function pipeline features. This allows Glimpse to use OpenGL Core profiles for version 3 and above.

These changes allow all parts of Glimpse to render correctly on platforms which do not support Compatibility profiles (such as MacOS).

Note that this update represents significant changes made to most parts of the Glimpse API, in addition to changing some portions of the public API.
