[Bf-python] IMPORTANT NOTE!

[joeedh]

Do NOT run EMesh.GetScreenVert/Face unless the mouse cursor is IN the 3D 
view window!  If you do, and if you mess up your window, putting the 3D 
view into top/orthogonic mode and then re-running the function in your 
messed-up window will fix this (or simply saving and re-loading).

Remember that EMesh.GetScreenVert/Face only gets the vert or face that 
is under the mouse cursor; it's the same function used by the mesh 
selection code.  It really should be GetMouseVert and GetMouseFace, 
shouldn't it.
