`MTL` is the abbreviation that Apple uses for Metal in all of their APIs. The only potential issue I might see with this prefix is in the native code where there could be name collisions between Java2D's names and Apple's names. Since we haven't run into such a collision, I don't think this needs to change, and wouldn't necessarily affect the Java class names anyway. If we were to consider it, `METAL` seems better than `ML` (which is too short to be descriptive and might suggest machine learning).
