The main reason for this is the compositing of both local and online covers with the same logic.
It was a problem raised in #146 with some covers getting stretched.
Changes:
- Renamed and simplified managers methods
- Created a generic `cover manager`
- Added more retryable errors to `steam api manager`
- Removed `local cover manager` and `online cover manager`
- Reduced dependency on `PIL`
Changed run_after, retryable_on and continue_on to be type Container.
We don't need them to be sets.
The performance gain of sets over small tuples is nonexistant
for in checks and the syntax is more verbose.
- Merged platform sources when possible
- Added URLExecutableSource class
- Moved replaced_by_schema_key to utils/decorators
- Better retryable exception handling in some managers
- Split SteamHelper into SteamFileHelper and SteamAPIHelper
- Delegated SteamRateLimiter creation to SteamAPIManager init
- Using additional_data for appid in SteamAPIManager
- Added Windows support for Legendary
- Stylistic changed suggested by pylint
- Added call stack to unretryable errors in managers
- Added existing itch cover downloading code
- Fixed importer not closing if no source enabled
TODO
- Tidying the itch cover downloading code
- If possible, make save_cover and resize_cover work in AsyncManager-s
