[swfmill] prerelease 0.2.12.4

[Ralf Fuest]

Hello dan,
I just tried 0.2.12.4 and it fails to compile. You have removed the
const keywords in swft_import_ttf.cpp and now gcc 4.1.2 on ubuntu 7.04
complains that there is an invalid conversion in these lines. After
adding the consts it compiled again.
