* Handling of context destruction is now handled individually for displays and canvases. For canvas, this allows it to destroy the pbuffer in addition to the display. * VertexBuffer now has better detection for data size changes, might prevent GL errors in certain cases. NOTE: VertexBuffer.updateData() is generally more stable than VertexBuffer.setUpdateNeeded(). Refrain from using setUpdateNeeded() .. its an internal call anyway. Using it directly could cause GL errors. git-svn-id: https://jmonkeyengine.googlecode.com/svn/trunk@7374 75d07b2b-3a1a-0410-a2c5-0572b91ccdca
