Configurable CSS

#2505955: Configurable CSS provides a solution. An alternative could be https://www.drupal.org/project/style_settings.

The attached patch fulfills the request but only for the caption font size.

To do:

• Include CSS variables for the Flickr Style sub-module.
• Add form field validation (e.g. font size must be a positive number).
• Extract the concerning CSS in a separate file to make that the rest still gets aggregated.

Added field validation. Also improves some existing ones by demanding specifically an integer instead of just a number that can be also a float. That didn't make sense for some fields e.g. those specifying a number of photos to display.

Attached patch extracts the concerning CSS in a separate file to make that the rest still gets aggregated.

Furthermore it adds the CSS variable for slideshow width, unit and ratio.

To move on to Flickr Style variables.

For a start the patch adds a configurable rounded corners radius.

Despite the #7 patch works as expected, we suspect that implementing it for many other CSS elements will over-complicate the code. Instead we wrote a patch for the Style (CSS) Settings module at #2512364: Extend to modules besides themes.

Once that is through we'll only have to wrap the intended CSS variables in comments and provide a UI to set them.

The attached patch does all the previous but instead leverages the Style (CSS) Settings module. This not only simplifies the code but is also universally applicable on other modules. Note that the patch includes a lot of other small unrelated improvements as well.

Does all the previous plus color support. Note that also the patch of #2528252: Offer a ColorPicker API form element type for developers must be applied on the Style Settings module.

Just saving some work.

First apply the patch of #2533666: Offer an image URL form API element for developers.
