Subject: Bugs fixed:

1915 - Data.JSON too large.  Reduced mesh size and limited precision of fp numbers
1381 - Background transparency in preview.
1740 - File Save As caused WebGL to stop animating.  Crossed RDGE IDs
1954 - Texture change from material popup broke screen rendering.   Set correct context on property change.
