Also, I've just noticed that the Render In Image patch in Quartz Composer 1.x actually has some settings the equivalent in QC 3.x lacks, like controls to set Filtering mode, Clamping, Anisotropy and number of MipMap levels. Is there any way to set any of these properties for an image in QC 3? I ask because I'm trying to disable filtering and set wrapping to Repeat, rather than Clamp for a 2D lookup texture I'm trying to use to create a Simplex Noise CIFilter.
Filtering is now handled by the Image Texturing Properties patch. I don't know if clamping/repeating options are available anymore though (they sorta work on core image filters, I think?). Anisotropy is still in QC, but it's not exposed anywhere anymore. Mipmapping is exposed, but non-functional. However, writing a plugin to enable it (on a per image basis) is possible, and produces valid output. You can see some of my research on that here: http://kineme.net/Discussion/GeneralDiscussion/unfiltration (when mipmapping is enabled, I noticed that anisotropy is actually enabled by default... so maybe it's enabled on non-mipmapped images as well, it just doesn't look too noticeable?)
Which filtering are you trying to disable? bilinear? there are a bunch of posts on the list, and an example in the developer examples section on that. Repeat/Clamped is possible with the Image Texturing Properties patch:
