This was written to address shaped windows, which can still generate a large number of rectangles, even in a composited environment. I think xeyes was the original test case; a full-screen xeyes window has a couple thousand rectangles, or about 64kB of data. I suspect an xeyes-specific optimization is not all that useful to keep around, but I fear that some user somewhere is taking advantage of this... -- [email protected]
