csswg/css3-background Overview.src.html,1.275,1.276

Update of /sources/public/csswg/css3-background
In directory hutz:/tmp/cvs-serv9850

Modified Files:
	Overview.src.html 
Log Message:
Added "Animatable:" lines for all properties. (Please check if they
make sense!) Also added a section explaining that animated transitions
between values depend on the css3-transitions module, which is likely
not to be REC before Backgrounds and Borders itself. (See ISSUE-210.)

+<p class=issue>[Proposed text for <a
+href="http://www.w3.org/Style/CSS/Tracker/issues/210" >ISSUE-210.]</a>
+It is expected that CSS will include ways to animate transitions
+between styles. The section <a
+href="http://www.w3.org/TR/css3-transitions/#animation-of-property-types-"
+>“Animation of property types”</a> of the <cite>CSS Transitions
+module</cite> [[CSS3-TRANSITIONS]] will then define how different
+kinds of values are interpolated during a transition. In anticipation
+of that, this module includes a line “Animatable” for each property,
+which specifies if the property can be animated or not.
