Maemo already uses softfloat and it's still slow. > Carl (cairo guy) said that he was taking care about API, not the core, > so he did the whole thing naively, however correctly, and will > optimize later... since Carlos (nokia) did give him a 770 in order he > can test it, we may expect something great really soon.

But we'll see, but I won't have high hopes, even if I *really* like cairo. regards, Koen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD8DBQFEv2pRMkyGM64RGpERApNSAKC3PQuxyo8v0puTf8i29nsWVIUCmQCgpBQU kaEE8gMnGX0KJe6sUI1xw5c= =X4AM -----END PGP SIGNATURE----- _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
