wxWidgets/src/gtk/dataview.cpp
Vadim Zeitlin 62265c2c67 Allow custom wxDataViewCtrl renderers to easily use attributes. 
Set up the DC passed to wxDataViewCustomRenderer::Render() to use the font and
colour defined by the item attribute by default so that any calls to
RenderText() from it will use them automatically.

Also added public wxDataViewCustomRenderer::GetAttr() to allow retrieving the
attribute explicitly in Render().

The column using custom renderer in the dataview sample now works as expected
in the generic version; the native ones will be corrected in the upcoming
commits.
