If I just resize the window, the composition doesn't rescale.
That's likely an issue in the way you deal with the NSOpenGLContext
If I follow
the workaround below, where I clear and set the view of the
GLcontext, the
composition rescales appropriately, however the values reported by the
"Rendering Destination Dimensions" patch don't update.
that's the QCRenderer issue I was mentioning earlier
How does the Quartz Composer App work, where the viewer window can be
resized dynamically, or displayed in fullscreen ? The composition
seems to
scale dynamically, without a problem, and I have tested the values
from
Rendering Dimensions and it updates perfectly.
