OpenGL error switch from surface to volume style

[Tom Goddard]

Got OpenGL error switching volume viewer menu from surface style to volume style for multichannel AICS-12_269.tif. Had switched one channel to plane style (right click on histogram, show one plane).

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.

Fixed.

Code created volume texture and then deleted it without making opengl context current. Did not make opengl context current because the Drawing that was being deleted was never drawn and did not know the opengl context. Fixed by not filling texture until it is actually drawn.
