BGE fix #20456 - 2.5: mouse position problem (offseted by 1 vertically)
In Blender 2.49 the win width and height were been calculated including an extra pixel (e.g. a fullscreen editor would be (width + 1) by (height + 1) )
In opposite to that, Blender 2.5 window/editor code were fixed to have the exact width,height size.
So although the BGE canvas code was still the same as 2.49 it was producing a wrong result.
I'm also adding some commentaries in the setViewport code. BGE is setting the viewports 1 pixel larger.
the setViewport command is been used as if one should pass (minx, miny, width, height), while it should be (minx, miny, maxx, maxy). I will take care of that later, if any one has extra comments on that, please let me know.

/* x1 and y1 are the min pixel coordinate (e.g. 0)
|
|
|
|
x2 and y2 are the max pixel coordinate
|
|
|
|
the width,height is calculated including both pixels
|
|
|
|
therefore: max - min + 1
