This makes demos render correctly on hiDPI displays,
while also demonstrating how to handle multiple resolutions.
The 3D in 2D demo now uses "3D No-Effects" for the 3D viewport,
which is faster to render. Thanks to this, 4× MSAA is now enabled
for a better result.
The background loading demo now uses mipmaps for better-looking images.
The material testers demo now samples mouse input in a
resolution-independent manner when panning.
Default clear colors were also changed in some projects for visual
consistency with the project's theme.
We used to broadcast player info on connect and have the server relay it
to other clients.
With this approach, each peer (including server) sends its own info once
to other peers as soon as they connects.
When a new player connects, it is notified of all the already connected
peers by the `network_peer_connected` signal.
Any already connected peer is also notified of the newly connected peer
by the same signal.
