Comment 3 for bug 1424629

I think the correct fix will be a bit more complicated, and possibly should wait for 1.7.

Currently, the select tool overrides OnCommit() to clear the tool layer (which hides the selection handles), and a ton of things implicitly rely on this behavior, like saving images (bug 887574) , the Deselect command, etc. This is why the selection handles disappear when pressing the Delete key.

I think the proper fix is to provide a way to get a list of the non-guide layers (which would fix the saving issue), remove the OnCommit implementation, and then ensure that the Select tool is properly notified when the selection is modified elsewhere in Pinta.
