glvertex

The glVertex library emulates the legacy OpenGL API, which has been deprecated in OpenGL core profiles.

It tries to bring back the following key concepts of the fixed-function pipeline:
* specification of vertices and attributes in immediate mode fashion
* specification of perspective, modeling and viewing matrices in immediate mode fashion
* matrix stack operations in immediate mode fashion
* control over a subset of fixed-function features

This does not imply that rendering performance is compromised using
the reenabled legacy OpenGL features. The glVertex library will map
the legacy features to the fast paths available in the OpenGL core
profile. For example, when specifying vertices in immediate mode, the
vertices will be automatically added to a vertex buffer object under
the hood. As a welcome side effect, the creation of vertex buffer
objects (VBOs) and GLSL shaders is much simplified with the glVertex
frame work.
