Juan Linietsky 6f0b4678e2 More 3D Improvements 
-=-=-=-=-=-=-=-=-=-=

-Sprite3D and AnimatedSprite3D support.
-Opaque pre-pass works, is compatible with shadows
-Improved shadow map rendering (can differentiate between plain opaque and opaque with shaders/discard/etc)
-Added option to use alpha discard in FixedMaterial
-Improved Glow FX, many more options (three modes, Additive, Screen and SoftLight), strength and scale
-Ability for Background (image or cubemap) to send to glow buffer
-Dumb Deploy of clients now actually works in Android
-Many Many rendering fixes, 3D is much more usable now.
