Screenshot dimensions

[kafleg]

Theme having invalid screenshot size doesn't restrict uploads or not showing any information in Theme Check Results: section in trac. Ticket, https://themes.trac.wordpress.org/ticket/104212

REQUIRED Screenshot dimensions are wrong! The ratio of width to height should be 4:3.

This is the message showing using the theme check plugin locally.

Also, there is information on the RECOMMENDED section,
RECOMMENDED Screenshot size should be 1200x900, to account for HiDPI displays. Any 4:3 image size is acceptable, but 1200x900 is preferred.

When a screenshot is larger than 1200x900, the theme check prompts two alerts.
Consolidating into one alert may be less confusing to the authors.

Ratio and size are two different problems, not one.
