One way to test this is to take these same fonts and use them in opposite colors; white text on a black background. If you see them as overly bright in this context, then it's not incorrectly computed alpha values, it's the lack of monitor gamma correction in the compositing computation. Another test is to use xgamma (on X servers which support it) and adjust the gamma value until the density of white on black text appears the same as black on white text. It may be that we'll want to revisit our simple linear computation in favor of adding a gamma correction (table/value) to the extension.
