Hey all,

Simply changing "square" to "curve3d" in the pix_coordinate example crashes PD due to gdb trace at end of this message. (PD 0.38-2 on OSX with Gem 0.90)

1. Create window 2. Load an image (I tired a number of JPG and TIF images)

attached is the test-patch.

I was really looking forward to using pix_coordinate to tile textures, any other way to do this?

Thanks all.
