@smsm1 can you create & post a testcase for this? the effect of the filter nesting is entirely dependent on the filters themselves.

The fontset duplication was fixed in #21, I'll check out this output to see if there's a way around duplication here, though I'm suspicious that this style layout simply creates...

Pushing this to 0.2.5: very high priority for a fix, but barely livable for the time being.

Okay, this is still a high priority, but I'm still kind of at a loss for a compact summary of the expected output and how this differs. I can see...

Experimental branch for this at https://github.com/mapbox/carto/tree/condense Since this work will likely change the output of a lot of tests and we don't have visual tests for carto, it's not an...

The main issue I'm seeing is that zoom rules are not properly taken into consideration when we're condensing filters, so we're generating 3 rules where there should be two for...

Finally got some profiling going: https://gist.github.com/4338438 Basic approach: ``` node --prof ./bin/carto -b test/rendering/issue20.mss ``` Check out v8, install, set ``` export D8_PATH=/Users/tmcw/src/v8/ ``` then ``` ~/src/v8/tools/mac-tick-processor >> analysis.txt ```...

Losing track of how this is a bug again - here's a reduced test case: https://gist.github.com/4339857 I get the 'extra filter generated' case, but that's at most adding a few...

Hey @gravitystorm - I agree. There are some filter-layer combinations that weren't really thought of in the early days of Carto and are handled poorly. At this point, there are...

Cool, need to read up Mapnik's source for this - kind of looks like the `` element can take the same attributes as `TextSymbolizer`, except for `placement`, I'd assume? /cc...
