Detailed Description

Regression tests for the GroupCell <-> EditorCell layout coupling.

Historically the GroupCell repeatedly stopped growing when its input EditorCell gained a line (by pressing Enter or by word-wrapping) once the cell had been evaluated and thus carried a "(%i1)" prompt label. Two bugs caused this:

1. GroupCell::RecalculateInput() only counted the height of the first cell on each line, so the taller EditorCell that follows the prompt label was ignored (the group kept the label's one-line height).
2. EditorCell::Recalculate() updated its height without invalidating the cached list geometry (GetHeightList()), so an incremental recalculation (the keypress path, which does not go through ResetSize()) read a stale, too-small editor height.

These tests exercise the real GroupCell/EditorCell/Worksheet/Configuration code (linked in via the wxmTestApp object library) so a future regression in either path fails the build.
