Update filters.py to allow tabbed filter inputs

Major revision to filter.py to allow the use of lists of tuples for which each tuple element on the list will produce a tab.  Tuples are also acceptable values, so no changes are necessary to existing filters.

Relies on additional revisions in tab_panel.py

Update tab_panel.py to support change in filter.py

TAG_Compound is usable as a dict.
Import OpenGL before all other modules.

Make sure error checking is disabled before any other modules get a chance to load the OpenGL module. Some Intel GMA chipset drivers will set an error condition when calling glGenRenderbufferEXT even though the framebuffer object is fully functional after initialization.
Change default FOV to 70.0
