Avoid duplicate StillRender() calls after interactive render.

When LOD was enabled and user interacted with the scene, we ended up with 2
calls to StillRender(). That was because the logic in
vtkPVGenericRenderWindowInteractor was redundantly calling StillRender(). Fixed
that.

BUG #14320: Turn on user-prompts on error on Windows.

In general turn off error prompts. This is where the process waits for
user-input on any error/warning. In past, we turned on prompts on Windows.
However, for client processes, we capture the error messages in the UI and
for the server-processes, prompts can cause unnecessary interruptions. Hence
we turn off prompts all together.

Remove using the new and old target_link_libraries signature on a target.

Starting with CMake 2.8.12 we warn about using the old and new
target_link_libraries signature on a given target. The problem is that
using the new signature changes the behavior of the old signature.

Document GPU-accelerated ParaViewWeb rendering using VirtualGL and TurboVNC

We have researched a method for using VirtualGL and TurboVNC in order to
provide hardware-accelerated rendering capability to ParaViewWeb, even in
situations where there is not a physical display. We need some
documentation of the steps required in order to reproduce this result on
the ParaViewWeb documentation site.
