Patch for 'turn' CSS angle unit type + testcases

Is it okay for the values in CSSPrimitiveValue.h to mismatch the values in CSSPrimitiveValue.idl?

[Dean Jackson]

No, it should be the same. I'll update the patch

updated patch

Updated patch for mitz's comment. Also updated test for Window properties since it changed with the new value for CSS_TURN.

updated patch

The values in the .idl come from <http://www.w3.org/TR/DOM-Level-2-Style/css.html#CSS-CSSPrimitiveValue> and I don't think they can be changed. Since the turn unit is not specified (yet?), I think it should be left out of the IDL completely and assigned a UnitType value that does not clash with the IDL-specified ones. It seems like the 100-and-higher range has been used for such "units".

Sorry about not thinking about all that before making my previous comment :(

[Dean Jackson]

DOH! You're right. The reason I shoved it in the list was I saw a lot of code in the CSS engine that checks for < and > various types. I don't know why the engine thinks the order of those enums is important, but I thought it would be less risky to put a new unit in the "right" place.

I'll put it at the end (100+) and see if anything breaks. The unit is defined in CSS3 but not CSS 2.1.

update with (hopefully) correct enum vals

Changed the enum values back to the specified values, and added TURN as 100+.

r=me, but as discussed in IRC, please don't check in the changed to the IDL.

[Dean Jackson]

Committed without the IDL change. This also meant the Window DOM testcase didn't need updating.
