- it does what mimetypes.get_from_data()
- .tiff is unused (afaik), so don't bother with it
- it is safer to analyze data for mime type (as data may not match provided mime type)
- when images are loaded from audio file tags, a check is done on valid format
- Info dialog Artwork tab now displays types and comment for cover art images
- a tooltip gives info about the source (url, caa url, local file, tag, ...)
1. Replace all \ with / in path not just last one so it works properly
on Windows.
2. Set combo index to show last used string
3. Strip leading zeros from numeric tags like tracknumber.
- last_ms has sub-milliseconds precision
- request_delay - last_ms can be < 1.0 (and it is a float)
- message use %d to convert value from float to int (so 0.5 is displayed 0 ms)
- QTimer.start() only supports milliseconds precision as int (so 0.5 will prolly be converted to 0)
- if delay is required, better wait more than not enough, so, ie., 0.7 ms delay is converted to 1 ms
- when delay is required, 0 delay doesn't make sense, first branch of the if condition handled that
- int(math.ceil(delay)) does the job
- int() cast is needed with python 2 (it returns a float), python 3 math.ceil() returns int
This hack was leading to cluttered debug messages since __repr__() was returning
status message in place of album's title.
Instead use a `status` property which is displayed in place of the title when it isn't None.
