Text element in SVG are not rendered correctly when the font-size is smaller than or equal to 1, regardless if coordinate transformations make it equivalent to large font size. This might be related to Bug 12172.

It looks like only integer point values are allowed for font-size in SVG, regardless of how a later transformation might change the actual display size. See also bug 12448. The test case there could also be a test case for this bug.

I think this might be 0.5px being rounded to 0, which AppKit maps to 12 (see bug 13891 comment #5 and below).

Created attachment 26281 [details] SVG incorrectly renders huge text The rendered text should fit cleanly in each grid cell, but you can see it does not. Firefox renders correctly.

I hope that the test-case can be useful webkit: wrong rendering of text, Firefox and opera correct rendering, Illustrator does not render the text. the rendering problem persist with version 4.0.5 (6531.22.7, r57720)
