Fix ArdourWidgets::Pane honor child min-size

Browse Source 
This doesn't yet correctly fix Pane::constrain_fract() constraints,
when moving the divider, but it does prevent child widgets from
being allocated with a size smaller than their minimum.

This fixes some layout and rendering issues (widgets that have
a too small allocation are not exposed and/or bleed into neighbors)
