Image size attributes

This manual tests consists of many use cases for different combinations of image attributes and styles:

• width (image width attribute)
• height (image height attribute)
• resizedWidth (image width style)
• resizedHeight (image height style)

Image in the editor should look like the image next to the editor (created from editor's output data):

• after initial editor load
  • the exception to this are inline images that have not been resized (because in the editor they have max-width: 100%)
• after resizing image in the editor

Note: Every time an image is resized, the code blocks below the editor are updated with refreshed output data and model. It's then easier to compare what has changed after resizing.
