annotate engine/core/video/opengl/renderbackendopengl.cpp @ 546:8fee2d2286e9

Rewrote the object serializing routines to use a "template" idea for loading an object from disk. This allows for multiple objects to load the same base object template but be unique on the scene AND have different values. Useful for say more than one gold stack on the ground with different gold values. TODO: fix the "spawn" console command.

ad7969d9460b A client can now specify a global color key to be used with all images. The default color key is (255,0,255) in RGB format. Also the client can enable/disable the color key feature by using the setColorKeyEnabled function in the EngineSettings class. By default the color key feature is disabled. fixes[t:451]
