/**
Move a cell into the grid or within the grid.
If the target cell is already taken, \p how will determine what to do:
If \p how is 0, the existing cell at \p to_row, \p to_col will be deleted,
unlinking the occupant from the grid. \p in_child will the be inserted at the
given location.
If \p how is 1, the old cell will remain intact, however \p in_child will be
unlinked from the grid.
If \p how is 2, the old cell will remain intact, and \p in_child will be
removed from the grid, but it will be stored in the transient list and
resized to the target cell position and size. If \p in_child is later
moved to an unoccupied cell, it will be removed from the transient list and
relinked to the grid. Rowspan and colspan are ignored here.
\param[in] in_child must already be a child of grid
\param[in] to_row, to_col move the child into this cell
\param[in] how 0: replace occupant, 1: don't replace, 2 = make transient
\param[in] how 0: replace occupant, 1: don't replace, 2: make transient
if occupied
\todo If the target cell is already taken, this function will remove the old
child from the cell and leave it in limbo (a child of grid, but with no
assigned cell). As this function is used to move children around with arrow
keys, it must be possible to move a widget past a cell that is already taken
without disturbing the existing system.
One solution would be to make the widget "hover", meaning, it will be registered
in Fl_Grid_Proxy as using the same cell as another widget. I am not sure at all
how to implement that yet. We could return the original cell, but that may have
different minsize, etc. . It would be better to have a temporary cell to store
all the information.
We must make sure that a hovering cell (or multiple cells) are a very temporary
solution, because all this information will be skewed if Grid::layout is
called, and all information is lost when we save the file for compilation.
We must show a conflict grid under or around the hovering cell!
Also mind the rowspan and colspan!
