[cairo] PATCH cairo-www: Simpler explanation for how to get sharp, single-pixel-wide lines

[me at beroal.in.ua]

Hi. Your patch deletes the existing answer that contains an explanation 
and alternative (IMHO, better) solutions. I am against this.

Automatic hinting is not the same as antialiasing. Automatic hinting 
adds .5 pixels if the line width is odd, 0 pixels if the line width is 
even. The effect of antialiasing is not defined in case when the line 
width is odd. The actual line width may be 1 pixel more or 1 pixel less. 
Therefore, automatic hinting should be a separate option with defined 
behavior.
