An error occurred in drawing the scene. Redrawing graphics is now stopped to
avoid a continuous stream of error messages. To restart graphics use the
command "graphics restart" after changing the settings that caused the error.

[Tom Goddard]

There are a few bugs here. First volume viewer is setting plane mode for just one channel then forcing an immediate redraw because the plane mode sets the slider value and the slider value change causes an immediate redraw. The other channels also have their region set to a single plane, but the remain in tilted slab mode, and tilted slab texture fill fails for single plane regions.

Should probably fix tilted plane so it does not fail for single plane regions, just show nothing.

Then fix volume viewer so it does not force a redraw when just the first channel has been switched to plane mode, all channels should change to plane mode before the redraw.

[Tom Goddard]

Fixed.

Problem was that 3D texture for single-plane region in tilted plane mode had wrong dimension. Another problem was the volume viewer was redrawing after just one of the 3 map channels was switched to plane. Fixed both problems.
