Immediate issue: using x position to index into a bitmap sampled at the input data rate doesn't allow for the disconnection between input rate and output speed provided by the flywheels.

Thomas Harte
16dfeb3fc8
Discards empty lines, yet makes some attempt at restoring transparency.

The two things conflict more than a little, so work to do.

Finally gets some pixels back on screen.
...
For now, just the raw scans, direct to the framebuffer, with no intermediate processing. But it seems to prove that at least some of the proper data is reaching the GPU.
