Changes

Fix textdata renderer trimming text without linebreaks too

Add a parameter that indicates whether the page is a left or right side

Textdata containing only \n will cause a linebreak

Change padding to be side-sensitive (4 sides). Make pages have less
padding towards the center.

Fix a race condition with rendering and initializing the mc variable

Change section list to be half as small (due to scale changes) and draw
section name as tooltip

Make width/height of sized elements available

Make book transformers available publicly. This is needed so that the
index transformer can be applied after custom transformers

Center the section list

Fix back-arrow position

Experimental "up" arrow thing for the back-to-index arrow

Change the tooltip rendering in books over to forge tooltip rendering

Translation utility
