It seems to me that this is going to squish the tatechuyoko vertically as well as horizontally. Are we sure that fits the bill? I expected you to do something with matrix transformations to squish in only a single direction.

Please remove this whitespace.

> Source/WebCore/rendering/RenderCombineText.cpp:133
> +            glyphOverflow.left = glyphOverflow.top = glyphOverflow.right = glyphOverflow.bottom = 0;

Is this necessary? Shouldn't the callee be doing this?

> Source/WebCore/rendering/RenderCombineText.cpp:159
> +            FontCascade compressedFont(bestFitDescription, style().fontCascade().letterSpacing(), style().fontCascade().wordSpacing());

Shouldn't we be picking between style() and firstLineStyle() appropriately?

> Source/WebCore/rendering/RenderCombineText.cpp:169
> +            computedSize--;

I don't think we should be looping on the order of the original font size. Isn't there a way to take bigger steps the further out we are?

We should make sure that RenderCombineText::width() uses the correct (shrunken) font too (it looks like it does from the .pngs but it isn't obvious)

I'm not sure if combining 12345 here is best. But I'm also not sure if keeping it uncombined here is best. Hrm.

Hardcoding this 6 here is probably bad, given the original font size could be humongous, making 6px way way too small relatively.

After some research, it appears that shrinking in both dimensions is fine.
