Follow-up Comment #1, bug #39535 (project octave):
Support for transparency is globally not implemented yet in the OpenGL
renderer. Although, transparency effects are possible in OpenGL, it's not
trivial and requires sorting primitives from back to front [1]. I had some
implementation in JHandles, but I never ported it to octave, IIRC I found is
sub-optimal.
This was a suggestion for a GSoC project, but it wasn't picked up.
