To recreate:

Open jit.gl.imageunit help file.

Add a jit.gl.texture foo after jit.gl.imageunit foo

Turn on rendering and load a movie (dvducks is fine)

Now make and send various a dim messages to each object. I haven’t
figured out what combination causes it, but ive gotten it to crash
about 5 times in a row now after sending various combinations of dim
messages to both imageunit and jit.gl.texture.

Id like to be able to have larger and smaller textures in the
pipeline, say for rendering openGL with @capture to a larger dimmed
texture to avoid any jaggies, and mix with DV or 320×240 video
incoming on the card, fwiw, thats my reasoning for experimenting with
dim/texture etc.

Expected behavior

No crash

Thanks!

BTW, I havent been able to isolate, but ive noticed since upgrading
to 4.6.2, my large patch crashes much more often. Its openGL and slab
chain heavy. Anyone else have issues?
