Bug 116745 – [CSS Shapes] rectangle and inset-rectangle do not properly handle rx and ry

• Component: CSS
• Status: RESOLVED FIXED

[Bem Jones-Bey]

According to the SVG spec (http://www.w3.org/TR/SVG/shapes.html#RectElement), the default value for rx and ry when one is unspecified is the value of the other. The current implementation always sets an unspecified rx or ry to 0.

[Bem Jones-Bey]

It looks like the behavior of rx and ry is more incorrect than originally thought, they should follow all of the rules in the SVG spec for the rx and ry parameters of rect.

Patch

Fix to repsect the rules in the spec, if ry is omitted, it defaults to rx, and if rx > width/2, rx = width/2, and if ry > height/2, ry = height/2

*sigh* I take this as a sign that I'm doing way too many different things. Will be fixing. Than you EWS for catching my fail.

Change for new spec behavior: the radii get now get scaled the as defined for border radius, not clamped as in SVG.

r=me but please add the assertions to be sure.

Was skeptical about about removing this if clause. Bem wants to add an ASSERT, since he says it can never be undefined. He should be right, since we always set the value on style resolving.

Ditto.
