Summary0015843: RC1 5.0 fails running normal, new, powerful Mesa
DescriptionI have a remote build of PV 5.5.0, RC1. When I run ParaView, I get the following in the output window:

Warning: In /projects/viz/paraview/src/ParaView/5.0.0-junk/ParaView4/VTK/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 549
vtkOSOpenGLRenderWindow (0x1451d00): VTK is designed to work with OpenGL version 3.2 but it appears it has been given a context that does not support 3.2. VTK will run in a compatibility mode designed to work with OpenGL 2.1 but some features may not work.

I then try to open a cylinder, and get the following on the client side:


ERROR: In /projects/viz/paraview/src/ParaView/5.0.0-junk/ParaView4/VTK/Rendering/OpenGL2/vtkShaderProgram.cxx, line 370
vtkShaderProgram (0x4005bd0): 0:2(12): error: extension `GL_EXT_gpu_shader4' unsupported in fragment shader

vtkUnsignedCharArray (0x62558d0): Unable to allocate 3757531591590 elements of size 1 bytes.

Server side looks like this:

However!!!!!!!!!!!!

Mesa 11.0.4 is OpenGL 4.1 compliant!

So, what's going on?

Due to stupid stuff in Mesa (internet search says something about patents), Mesa 11.0.4 implements OpenGL 4.1, but a glGetString(GL_VERSION) returns that it is only OGL 3.0 compliant.

Hack to get around it: set MESA_GL_VERSION_OVERRIDE=3.2

But, we must have ParaView work as follows:
* Work with new Mesa, without having to set an environment variable.
* Work with older versions of Mesa (at least for a while), and never, never crash.

 OK to make project Sandia if appropriate.

 Yes, so MESA seems like an odd beast in that Mesa supports recent OpenGL versions but some of its drivers do not. I believe the pure software driver works fine. This page shows a nice list of drivers that do support all that we need

https://secure.freedesktop.org/~imirkin/glxinfo/glxinfo.html#v=Mesa%2011.0.0 [^]

but we still need to gracefully handle the case where Mesa is using a hardware accelerated driver that is tied to old hardware. I have made the SupportsOpenGL() method work in VTK/OpenGL2 so that PV should be able to gracefully query for support prior to trying to render and handle it nicely. With that we should be able to track down what Mesa drivers are causing issues.

    BUG 0015843: Add support to test OpenGL version.
    
    Added checks during initialization of a session to validate OpenGL
    version support. If not adequate a dialog will be popped up warning
    about the same. If the OpenGL version of server side alone is
    inadequate, then remote rendering is disabled. If OpenGL version on
    client is inadequate, then we pop up a dialog and abort.

 Much better.

Tested Linux, master, remote server (Chama).
