Call SetAttr() to store them in wxDataViewCustomRenderer before rendering it and also honour the attributes in RenderText() (by reusing the same code we already use for wxDataViewTextRenderer). The attributes now work correctly in dataview sample under wxGTK as well. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@62596 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
