informatic a7dbf25588 hswaw/signage: reuse compiled shader, better error handling 
Shader will now only be recompiled whenever its code changes. This helps
with hangs on node transitions on underpowered devices.

If shader reload failed an error message will now be rendered over an
existing shader.

File load errors are properly handled.

love2d signage
===

As used in digital signage displays in HSWAW.

Originally hosted on code.hackerspace.pl/informatic/love2d-signage, now in hscloud.


Building & Running
---

Run the following in hscloud root:

    $ nix-build -A hswaw.signage.prod
    $ result/bin/signage

If the result doesn't run and complains about OpenGL not being available, try building the 'local' target instead, which will use your host `<nixpkgs>`:

    $ nix-build -A hswaw.signage.local

For non-NixOS systems you'll need something like `nixgl` to work around Nixpkgs-GL-on-Non-NixOS badness anyways.

In order to run the app in more of a development environment with hot code reload and such use:

    $ ENV=dev $(nix-build -A hswaw.signage.local.runtime --no-out-link)/bin/love hswaw/signage/

Custom configs
---

You can either modify config.lua and rebuild, or specify a custom config at runtime by setting the `SIGNAGE_CONFIG` environment variable.
