Added Frist basic version on the VectorRenderModule, that allows scripts to do some basic drawing onto textures. Currently the method the scripts have to use is most likely not the most user friendly, but this should improve soon. And hope to allow SVG files (either loaded from a web site, or even script created) to be used. I will add a page to the wiki tomorrow, until then http://www.pastebin.ca/934425 is a example c# script that can be used to get a bit of a idea.
Also added osSetDynamicTextureDataBlend and osSetDynamicTextureURLBlend that will allow the various textures to be blended together, but currently there are still a few bugs in them. So not ready for use yet.
