Right now it runs ~12 fonts that have ~3k glyphs each; this is why it's so large. I think the best solution is splitting up runs of the tests to limit it to specific fonts and glyph ranges. That way you can download the smaller subset of tests that fail.

The scripts are already basically structured to do this so adding that should be easy. If you could give me an idea of how you would like the config file structured I can write a parser easily enough.

I've never been the best at design. If someone can give me a design mockup or something similar they'd like it to look to though I can make it match fairly easily.

Here is a small subset of the glyphs. I've manually modified one in gimp to show the image diffing.

Thanks; I will try that in the next few days, hopefully.

This looks very good, thanks!  Indeed, the archive size of almost one
Gigabyte is far too large for practical purposes.  We have now to find
solutions in the next month how to refine that.

What do you think about using a control file that specifies which
fonts to use, which glyphs in those fonts to use at which sizes,
modes, etc.?

I think some CSS magic to make the results more pleasing would also be
nice, but this is an extra of no particular importance currently.

I *have* to see the image comparison live :-) When testing this
locally, I'll try to temporarily introduce a bug – since this depends
on the selected fonts I also have to do some trial and error to find a
good spot to do that.

The most important thing IMHO is that you (manually) prepare a subset
of the large report now (not larger than, say, 1MByte) so that other
interested persons can quickly download it to have a look.
Additionally, it might be helpful if you could send some screen shots
to the list.
