The threads example shows a plain white window and then exits with

(exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

The offscreen example panics with

Fix for the offscreen example not working on Windows.

Partially addresses #181.

Note that after this fix, the example still doesn't halt but it finishes the main function successfully and produces the png with the colorful triangle.

Not sure if related, but I got the following error on Windows with the latest offscreen example (7c78d0c):
