Multiple vertex streams support

[jamesmintram]

I have per vertex data which I would like to pass to the vertex shader by using more than one vertex buffer. (changing the memory layout to interleave this with the existing vertex data is not a great option)

Is this possible with BGFX? If so, what is the best way to do it?

It's unsupported right now, but I plan to add vertex streams.

What's the recommended way to organize and update vertex buffers with data that changes at different times?
For example, a deformable mesh could be defined with a constant index buffer (no problem), similarly constant vertex colors (or texture coordinates), and animated vertex positions that change every frame.
Colors should be in a static buffer, positions should be in a dynamic buffer, but if they have to be in the same buffer, presumably a dynamic buffer, memory bandwidth is going to be wasted refreshing actually unchanging vertex colors.

Added support a while back.
