[wpigui] Hardcode window scale to 1 on macOS (#3135)

This fixes an issue with scaling on Retina displays where the frame
buffer size was double that of the window size, resulting in a content
scale factor of 2. This scale factor caused elements to appear too
large, even on the smallest zoom setting.

This change does not affect external monitors on macOS because the
reported content scale was 1 anyway.

+Upon pushing a tag, a release will be built, and the files will be uploaded to the releases on GitHub. For publishing to the marketplace, you need a Microsoft account and to be added as a maintainer.
+
+## Publishing GradleRIO
+Before publishing, make sure to update the version in build.gradle. Publishing must happen locally, using the command `./gradlew publishPlugin`. This does require your API key for publishing to be set.
+
+## Building the installer
+Update the GradleRIO version in gradle.properties, and in the scripts folder in vscode, update the vscode extension. Then push, it will build the installer on azure.
