Gentle People:
A question on Cairo: The X Y inputs to Cairo drawing functions are
type double.
Dose this imply that pixel or line spacing could be less than 1.0?
Could the spacing be say 0.5 or 0.25?
No.
However, there is an important semantic sense to units in Cairo that end in .5, which you and should read more about here:
Understanding what is described there is critical to working with Cairo, and more generally to almost any computer graphics based on pixel displays (ie. everything at this point).
