compile error in piet-direct2d #337
Description
Hello.
Rustc is update to 1.47.0. I am using Windows 7 and my default toolchain is stable-x86_64-pc-windows-gnu.
I wanted to test cross platform with a little example. No worries when I compil in linux or macos, but in windows there is that compil error.
