Fix typos

[ericphanson]

This PR is also an issue-- I hope that's alright.

I'm trying to figure out how to use boundingbox; even with these fixes, e.g.

face= FreeTypeAbstraction.findfont("Times")
FreeTypeAbstraction.boundingbox("abc", face, 1f0)

fails with an error

Would appreciate any help :)

I'm trying to write a function (str::String, face::FTFont) -> img::Matrix{UInt8} where I don't have to know the size ahead of time like with renderstring!, and I thought boundingbox might help.

Wow :D Not sure what happened, that I actually ended up committing this... I fixed the issues in: https://github.com/JuliaGraphics/FreeTypeAbstraction.jl/pull/40 Thanks for starting this!

I was surprised too, haha. Thanks for the quick fix and release!
