comparison layer/TextLayer.cpp @ 1547:e6362cf5ff1d

Pass a y-coord, optionally, to Layer::snapToFeatureFrame. This is necessary for BoxLayer which needs to coordinate its snaps with the box it is highlighting for editing. Then in BoxLayer, merge getPointToDrag and getLocalPoints into a single getLocalPoint and use this throughout.

 //!!! too much overlap with TimeValueLayer/TimeInstantLayer
