this creates a renderer too often.
since the purpose of the cache is avoid to create renderers this is not=
good

used when the display size matched the size hint exactly. This patch tries to relax \
this condition by searching for the smallest size hinted element that is still bigger \
than the display size (in order for the element to be chosen, it also has to have the \
same aspect ratio). If no such element can be found, it falls back to the normal \
element id as passed.
In order to speed up the lookup (and because it appears to be impossible to access \
the DOM of an already loaded SvgRenderer), all size hinted element ids are stored in \
SharedSvgRenderer at load time.
I think it would be good to change the QRegExp based id fetching into a proper DOM \
traversal. Are there any convenience functions in KDELibs that allow easy iterating \
over all elements (couldn't find any) or do I have to implement that myself based \
on Qt's DOM classes?
Please tell me what you think... Have I missed something?</pre>
