I'm trying to debug a strange readback issue in a large software system. I find it quite useful to dump an image of what's in the framebuffer at various points in the process. I've grabbed a write_ppm method out of an (OS?)Mesa demo, and I call it periodically to see what I've got in the buffer. There's a point in time where I have a good buffer, and then there's a point in time where, if I had to guess, I'd say some code is interpreting the buffer as `GRB' data.
I'd like to dump the buffer while I'm in Mesa at this point -- e.g. every time _swrast_ReadPixels gets called, write out an image with what Mesa would return. Seems like someone else might have found a use for something similar before. Is there anything in Mesa to help me out here, or should I just ad hoc hack in the image dump myself?
