Verify the GPU can actually support the required feature set (Like OpenGL 4.3 for compute shaders) and throw a warning/error otherwise.

Incomplete change to address OpenGL version checking, ref Issue #66

Committed incomplete test to a new branch opengl_version_check (bea1a89).

Issues:

/* FIXME: This code does not currently function correctly.
 * Issues:
 *
 * - The version returned is not the highest OpenGL version the system supports.
 *   This is due to how GTK is creating the OpenGL context, and how OpenGL deals with backwards compatibility.
 *   We should probably have GTK create the OpenGL context, requesting version 4.3 as the minimum required version.
 *

WaveformArea now requests 4.3 core profile during startup. Can you re-test your branch with this change and see if it properly detects what we got?
