Bug 888 - Validate CPU Runtime Performance: X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..)
X11GLXGraphicsConfiguration.GLXFBConfig2GLCapabilities(..) ran over all FB configs and for each it grabbed
native config values separately. Fetching them in bulk mode saves around 7% of this function's cost.
Also reuse XRenderPictFormat instance for 'XRenderDirectFormat XRenderFindVisualFormat(..)' call,
saving a few NIO creation cycles w/ StructAccessor.
Biggest savior is X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig()'s
fast path w/o chooser and usable 1st FBConfig. Here we only issue 'GLXFBConfig2GLCapabilities(..)'
on the first valid entry.
Test w/ 50 X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationFBConfig() invocations:
- pre change: 1.708 ms
- post change: 650 ms
Time is no spent almost solely on native glXChooseFBConfig (546ms).
