*
* 3) If the type is the same, and it needs conversion, make sure it stayed at the same place. Moving
* converted bytes requires a reconversion of the whole buffer
*
* 4) The stride is not a reliable indicator for existance, as it can be 0 if an attribute stays static
*
* 5) If we used a vertex buffer before, and we aren't using one now(wouldn't be in this codepath
* otherwise) then we cannot compare the strided structures. Vertex shaders use numbered attributes,
* fixed function pipeline uses named once. For example, a vertex shader could have used converted
