Each character has a default width. If you set the Font Size the width
is scaled and normally you will not get an integer value. With
antialiasing you don't need to round, but you can paint the characters
nicely at half pixels.
If you now want to draw the second letter in a word you must start at
half pixels to get the same antialized text.
