Fixes with font outlining, #2.
Fixes with font outlining, #2.

- Added proper scaling for outline width

- Text width counted manually now, because TTF_Size() return strange
result for font with outline.
For example, for font FayesMousewriting_quotemapped.ttf, size=48,
outline=0, text="Load Game" it return width = 152.
For the same text, outline=2 it return width = 156.
