improved limit()/clamp() behaviour - now it doesn't call nor(), reusing the (needed anyway) len var, resulting in *one* scl() call instead of *two*. Also, we use cached len, so that we don't have to calculate it twice. Mostly benefitial for Vector3 class.
a brand new ObjLoader/MtlLoader class pair, AFAIK completely compatible with existing interfaces; fixes issues https://github.com/libgdx/libgdx/issues/2436 & https://github.com/libgdx/libgdx/issues/2441
added copy constructor/cpy() methods to both BitmapFont & BitmapFontData & delegated setScale to data, allowing e.g. easy creation of scaled variants of BitmapFonts.
added "emitDefaults" to allow forcing emiting default values on writeFields call
fixed some raw types in method signatures, to allow using them without rising warnings during compilation
fixed some raw types in method signatures, to allow using them without rising warnings during compilation (part 2)
implemented constants needed for fixing https://github.com/libgdx/libgdx/issues/2524 - fully backward compatible
preliminary fix for https://github.com/libgdx/libgdx/issues/2524 - intended to be fully backward-compatible
Java Collections <-> libGDX collections bridge classes (views); fixes issue https://github.com/libgdx/libgdx/issues/2359
