We now use the virtual screen’s size/position instead of the X root
window for the grabwin (grabwin = the area in which the pointer may
move when resizing).
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.
