Scene opengl has a callback for when we have a GL error. One of the
handlers for an error calls scheduleVboReInit - the comment next to it
explicitly mentions Nvidia.
When we get here we schedule a reset of the vertex buffer, via a timer.
When the timer is caled we have no idea what GL context was last
current, if it's not the currect context then the main scene
GLVertexBuffer will be deleted but not correctly re-initialised.
We have a very common crash with a corrupted GLVertexBuffer...
