**Support CSS background property in labels/text renderer **

PR Description:

This commit adds support for the CSS background-color and background-image properties when used with HTML labels.

• Backgrounds are supported for block items (eg <div>) or inline items (eg <span>)
• For images, the CSS should be formatted as background-image: url(xx). It supports local file paths, http links, or base64 embedded content
• Backgrounds are not supported for curved text
• HTML backgrounds are always rendered above any background shape for the label, and below drop shadows/buffers
