    nice :)

    You'd probably gain performances by avoiding the conditional branching. I'm not sure why you use two channels. you could use a single gradient, tighten the range with a multiplication and offset the values by your _Amount. Saturate() and voila, you'd even have a nice anti-aliasing for free :)

    i guess you know this one http://www.valvesoftware.com/publications/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf
    not the subject but close

    I'm pretty sure you are not bound by the precision of the texture itself (8bits), but rather the precision of interpolators (probably half or float).
    You could use a highres uncompressed texture for the mask (inside/outside the letters), such as alpha8, and then use a lower res texture as a gradient source. The bilinear filtering and the interpolators should do the rest.

    Nice stuff anyway, thanks for sharing :)
