virtualx-engine/drivers/gles3/rasterizer_gles3.cpp
Juan Linietsky 0f7af4ea51 -Changed most project settings in the engine, so they have major and minor categories. 
-Changed SectionedPropertyEditor to support this
-Renamed Globals singleton to GlobalConfig, makes more sense.
-Changed the logic behind persisten global settings, instead of the persist checkbox, a revert button is now available
