[Paraview] Update: Upcoming ParaView Releases (4.4 and 5.0)

[Utkarsh Ayachit]

Lester,

ParaView 4.4  won't have any major OpenGL related changes so it should work
on platforms ParaView 4.3 or earlier worked. ParaView 5 (with its use of
OpenGL 2.1/3.2 features) should indeed still work on Windows 7/8 with
relatively modern drivers. Note, OpenGL 3.2 is still quite old (~2009). If
you're using remote-desktop, however, you may want to switch to using VNC.
Remote desktop uses a software OpenGL implementation, which (when last I
checked) was only OpenGL 1.1 compatible.

(cc-ing Ken to correct me if I am mistaken)
