DispatchTimer Priority for drawing in OpenGLControl

Hi,

Our users complained about a poor performance of our application when an OpenGLControl was open.

I tracked that down to the Dispatch timer priority which was 10 (DispatcherPriority.Send) which is the highest priority.

I lowered that priority to 7 (DispatcherPriority.Render). Doing this, reduces fps a little bit, but the rest of the application stays responsive.

Maybe that should be changed in the next Version?!

Cheers Thomas
