Aevyrie b3aff9a7b1 Add docs and common helper functions to Windows (#4107) ... # Objective - Improve documentation. - Provide helper functions for common uses of `Windows` relating to getting the primary `Window`. - Reduce repeated `Window` code. # Solution - Adds infallible `primary()` and `primary_mut()` functions with standard error text. This replaces the commonly used `get_primary().unwrap()` seen throughout bevy which has inconsistent or nonexistent error messages. - Adds `scale_factor(WindowId)` to replace repeated code blocks throughout. # Considerations - The added functions can panic if the primary window does not exist. - It is very uncommon for the primary window to not exist, as seen by the regular use of `get_primary().unwrap()`. Most users will have a single window and will need to reference the primary window in their code multiple times. - The panic provides a consistent error message to make this class of error easy to spot from the panic text. - This follows the established standard of short names for infallible-but-unlikely-to-panic functions in bevy. - Removes line noise for common usage of `Windows`.		2022-03-08 00:46:04 +00:00
