Many of the OpenGL tests were for RenderingCore API, others were from
RenderingImage and RenderingLabel. Moving them to more appropriate
locations, this makes it easier to validate some of the OpenGL2
implementations now we have a concept of multiple rendering backends.

This enables us to compile the Geovis module without depending on
the OpenGL implementation, after discussing it with Aashish this
class may be deprecated and removed in the future.

If the module is enabled always override. Also exclude the backend
modules from the build all option as they are mutually exclusive of
one another.

There may be a better way to do this with module logic, but for now
ensure we don't try to build both.

Made the vtkGUISupportQt module work, moved the other QtOpenGL module
to OpenGL backend only for now - uses vtkgl/extension manager stuff.

These can only build with the OpenGL backend.

This needs fixing more completely in the future to use the correct
API, but it gets most of the tests passing for now.

This will enable us to switch the backend at will, the OpenGL works
whereas the OpenGL2 needs some additional improvements mainly to
use point sprites (where most of the tests are failing.

This adds a concept of a rendering backend to the module API, with
an OpenGL and OpenGL2 backend. They are mutually exclusive and one
or the other should be selected (or None in the case when rendering
is not requested). This needs a little more work as the default
backend enables rendering when the group is disabled at this point.

This now gives us a vtkRenderingOpenGL2 that has most of the same
classes as vtkRenderingOpenGL - the two will clobber each other's
headers, symbols etc and so can never be built/linked at the same
time.

Unfortunately a lot of classes SafeDownCast or dynamic_cast to the
derived OpenGL forms of the classes in vtkRenderingCore, and so
using a different class name presented significant issues despite
the fact that these classes are (in an ideal world) implementations
of the API in vtkRenderingCore for OpenGL 2.1 and above.

Check it for NULL before deleting it, in the case of the new
rendering code no override is provided and this is NULL.

This required several classes to be copied over, they may not stay.
It also required me to port many calls from vtkgl to GLEW, and get
rid of checks for features in OpenGL 2.1 or less. The extension
manager has been removed, and its functionality replaced.
