Enable anti-aliasing

[dimchansky]

The hands on the clock look not anti-aliased:

Does the fyne-io/fyne support anti-aliasing? Can it be enabled for examples?

Thanks for the report. It was blending but incorrectly - that has been resolved upstream.

go get -u fyne.io/fyne

Then running the example again should work as expected.
