Thus, no more flickering because the window was first mapped and then
moved. Especially users of multiple monitors should be happy now ;-).
Rather radical change, though, so be prepared for problems.
This is a relatively big change, however all cases should be handled by
now.
Because the function to do graphical resizing got rather large, I’ve created
a new file src/resize.c for it.
This fixes ticket #35.
