A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything.

Keeping a buffer permanently bound is apparently illegal. So back to copying in on demand. Which I think still improves on synchronisation, but not much.

As messy as it is, this use glMapBufferRange to avoid explicit buffer submits.

Still stepping slowly towards a working composite mode, switched the RGB sampling function to returning a vec4, which may be of benefit to any machine with a brightness part of an RGB signal, and started edging towards at least having the correct GLSL programs ready for converting composite output.

Added a first attempt to generate output scans for composite mode. So this in theory completes the CPU side of composite operations. Though I'm sure problems will reveal themselves.
