fit-content

[GoncaloBastos]

Spin-off from #114:

Moving discussion regarding a new feature where a parent block size is driven by its content.

Proposed API

new ThreeMeshUI.Block({
   width: 'fit-content',
   height: 'fit-content'
});

Functionality

width
Two separate cases exist when using width: 'fit-content'

• root object: When the attribute is set on the root object, content is allowed to grow in width indefinitely. Only apply mandatory linebreaks.
• non-root object: For non-root objects, width is capped at the parent's width.

height
Only a single case for height. It should always match content height, regardless of its parent's height.

width & height
Should the content exceed its maximum dimensions, it should overflow from the bottom - see fiddle
