[ft-devel] ouch! (burned by premultiplication)

[Alexei Podtelezhnikov]

Werner,

I cannot believe it.

Using premultiplied BGRA is a very bad decision. The savings are
minimal but the cost is huge: it has to be undone for gamma
correction, which loses precision and is, therefore uncacheable in our
tools.

Ouch! Ouch! Ouch! Please introduce FT_PIXEL_MODE_RGBA without premultiplication.

Thank you,
Alexei
