* Fix various issues caused by #3679 - The arguments for the 0th dummy vertex buffer were incorrect - it was given an offset of 16 rather than a size of 16. - The wrong size was used when doing `autoBuffer.Get` on a converted vertex buffer. - The possibility of a vertex buffer being disposed and then rebound can rebindings to find a different buffer where the current range is out of bounds. Avoid binding when out of range to prevent validation errors. - The above also affects generation of converted buffers, which was a bit more fatal. Conversion functions now attempt to bound input offset/size. * Fix offset for converted buffer
