CHANGED: On pasting multiple rows from a clipboard to the end of a
grid, the grid is automatically expanding (appended needed number of
rows). In general case the grid expanding on pasting is inappropriate.
Rows must be added by tools like a button or a menu command etc. In some
cases rows cannot be added at all. So we must paste only the part of
the clipboard that fits between the cursor position and the end of the
grid without a grid extending.
CHANGED: First click sets a cursor to the specified cell, second click
activates editor (current realization, where first click activates cell
editor, is very buggy especially with cells selection).
Set cursor on cell of reference on mouse left click in Fields editor of
Eeschema.
Allow copy of a single cell demarcated by the grid cursor.
Paste of lib_table s-expressions should always start at 0,0.
Let caller or specialized sub-class do auto-sizing; don’t
do it from within the base GRID_TRICKS.
Don’t start GRID_TRICKS menu IDs at -1; wxWidgets doesn’t
like it when you get to 0.
Add column visibility menu.
