Subject: [9fans] drawterm update to gui-osx/screen.c
Topicbox-Message-UUID: c16c4a6e-ead4-11e9-9d60-3106f5b1d025

This is the same patch that I applied to devdraw, just in the current
drawterm code base.  kEventAppShown gets called when the application
comes out from being hidden/screen saver/etc.  Without catching it and
passing it on, we get a blank white window until a resize or
fullscreen event occurs.
