@TODO:
+- find usages (textDocument/references)
- clip highlight to buffer rect
- different highlight colors
+- --help, --version
+- framerate-cap setting
- highlight-enabled, and highlight-auto
-- more LSP stuff:
- - find usages (textDocument/references)
- handle multiple symbols with same name in go-to-definition menu
- :go-to-cursor-definition
- test full unicode position handling
