NodeAttribute * SelectedAttrs::FindFirst ( CCRuntimeClass * AttrType = (CCRuntimeClass*)CC_RUNTIME_CLASS(AttrFillGeometry) )

Scans the selection for attributes. Replaces AttrFillGeometry::FindFirstSelectedAttr without relying on global variables!

Author:: Phil_Martin (Xara Group Ltd) <camelotdev@xara.com>

Date:: 20/4/2005

Returns:: The first AttrFillGeometry it finds in the selection. or NULL if they're aren't any.
