What's Smooth Shaders for?

[orklann]

Hi,

In your post, you did not mention anything on this smooth shader, can you make some simple explanation on this shader? I can not figure out why this shader can improve the smooth of the glyphs.

Thanks.

This is for drawing anti-aliased lines, which are used for decorations such as grid lines, brackets, and the square root symbol. It's not used for text rendering.
