Start plotting something.

The first plotting method was removed from profile.c
to profilegraphics.cpp and some conversion ( almost 1 to 1 )
was made so that the code could work.

Since the code is big - this commit has just a part of it
working - it plots the grid. but already works for testing
the resizing of the window and Zooming ( unimplemented )
