Divide-by-zero error in linear-gradient code

[lojjic]

See forum posting http://css3pie.com/forum/viewtopic.php?f=3&t=4 -- there is a divide-by-zero error when the element has dimensions of zero.

We should probably avoid performing any rendering whatsoever when the element has no dimensions.

Also see issue #39 -- this error is reproducible by setting a PIE element's ancestor to display:none.

This issue shouldn't be closed as the error still occurs (and is particularly irritating).

You're using the most recent code from GitHub and still seeing this? Can you post a testcase?

Problem occurring also at line 3133 of the uncompressed .htc when applied to element with no dimensions (display: none)

Plastered over with the following kludge replacement for line 3133; works in my situation but not sure if would work generally:

if (w > 0 && h > 0) {fill.position = (0.5 / w) + ',' + (0.5 / h)} else {fill.position = '0,0'};

This has already been fixed in the latest code: a76770d
