Wonderland Engine 1.4.6 - Texturing Improvements and Bugfixes

This release features improvements the texturing system and many bugfixes.

Because Wonderland Engine automatically atlasses all your textures, advanced systems are required to generate mip-maps efficiently and ensure wrapping textures work properly. Similarly, the dynamic upload of textures (e.g. from HTML Video or Canvas) needs special care and got a significant performance boost in this version.

We backported many bugfixes from the upcoming 1.5.0 release, especially for physics simulation.
