[Gambas-user] gb3: gb.opengl will not render alpha channel of 2D texture

I've been researching this for hours and nothing I try works. The image 
used for the texture has an alpha channel, but it is displayed as black 
instead of transparent. I'm starting to think that the line:

Gl.TexImage2D(t1)

isn't passing the presence of an alpha channel to OpenGL, but that's 
just a guess. Normally you specify the image format there, but those 
parameters aren't supported yet in the gb3 implementation.

The project is attached. You can move the little wizard around with the 
ASDW keys and rotate with the QE keys. Any help appreciated...I'm going 
crazy and am calling it quits for the night!
