+/// GL::Workaround::needsExplicitGenerateMipmap
+/// GL::Workaround::X1600DepthBufferCopy
+/// GL::Workaround::HD2600DepthBufferCopy
+/// If you find that you need to work around additional driver bugs, add a new setting
+/// of the form GL::Workaround::<name> and set it to false in GFXGLCardProfiler::setupCardCapabilities()
+/// Enclose your workaround code in if(GFX->getCardProfiler()->queryProfile("GL::Workaround::<name>")) {
+/// <workaround> }
+/// Remember to set the work around to true in the card profile script!
