Various research points for compressed textures, atlasses, arrays and so on in QQ2

Please add discussion points as sub-tasks of this epic.

The main ideas on the tables are:

• Compress image assets into compressed texture formats
• Generate texture atlasses at compile time
• Consume everything from Qt Quick 2 in an easy way
• Have proper build system integration for all of this, so that it doesn't become the exceptional case but the norm in the majority of the projects.
