Bug 122567 – Add support for minsize/maxsize attributes

• Status: RESOLVED
• Resolution: FIXED
• Component: MathML

[Frédéric Wang (:fredw)]

The minsize/maxsize attributes allow to specify minimum and maximum size for vertical operators. This should be easy now that MathML length parsing is implemented.

See test 46 and 47 of the MathML Acid 3 test:

Looks like stretch operators are being stretched more than usual in this test. Does it just need to be updated?

I guess so but I can not see the screenshot. I have not been updating anything on this test but the Mac text reference, since for some reason that was the only thing the bots complained about.

The patch switches from int to LayoutUnit for stretch sizes so I expect that might changes slightly the size. Also, the default minsize (1em) is now taken into account so the small operators may be a bit larger.

I think this is a consequence of

https://bugs.webkit.org/show_bug.cgi?id=119043 (that fixes stretchy error on the top)

and 

https://bugs.webkit.org/show_bug.cgi?id=124827 (that makes these fences symmetric per the op dictionary)

but the reference has not been updated since the bots only attached the Mac text output.
