***********

Several DataGrid fixes. We remove checking for new edit sessions during focusIn handling and start the edit session on mouse activity, fix the calculation of maxHorizontalScrollPosition in a corner case, measure fonts in the header correctly, end the edit session on a dataprovider reset, handle having no scrollable columns.

Also update TextInput to more aggressively reset selection when used as a renderer
