d03291eeb1 gui: improved FPGAViewWidget::paintGL() performance 
Profiling revealed that memcpy() in QOpenGLBuffer::allocate() had been taking
the most time during paintGL() calls. I've been able to take the CPU usage
down to about 1/4 of its previous values by caching elements in VBOs and
updating them only after subsequent calls to renderGraphicElement().
