lock buffers Hard (if any).
"slow call", so batch them. nlassert good TType. return is the VB info. NB: if the buffer is locked while a reallocation occurs, then the buffer is unlocked.

setup driver, and test for possible VBHard reallocation.
if the VBhard/Driver has been deleted externally, Vertices are lost. The vertex buffer is reallocated and reallocationOccurs() return true (see reallocationOccurs()). to do anytime you're not sure of change of the driver/vbHard state.
Note: the vertexProgram is created/changed here, according to driver, and TType. -
