  GUI2/Styled Widget: enabled the virtual init function

I need this for some upcoming changes to the minimap widget that require an initialization
step on after canvas creation.

  Added new minimap drawing method that works wholly with textures

I've left the old getMinimap function alone and added a new function that will eventually replace it
that utilizes texture rendering to a given texture instead of relying on surface blits and scaling.
This has the benefit of, well, reducing surface ops, for one, as well as removing the need to create
a new texture from the minimap surface every time it's updated.

  GUI2/Canvas: allow the default draw routine (shape drawing) to be overridden

Previously widgets that wanted to implement custom drawing behavior overrode styled_widget::impl_draw_background
or impl_draw_foreground. Those functions in the base class simply called the canvas render methods. Some widgets
such as the minimap ignored that rendered the contents on their own.

This new method allows rendering directly to the canvas's texture, meaning all the caching and sizing is already
handled by the canvas and doesn't need to be done by the widget; everything's always the right size and redrawn
when necessary.

  GUI2/Minimap: refactored drawing code

Instead of using the minimap surface method (which was getting converted from surface to texture every
draw cycle since the caching mechanism the canvas implemented wasn't available and the weird custom
cache the widget implemented itself didn't seem to do actually do anything) we use the new render-to-
canvas-texture method which is a lot cleaner and should be a lot faster. This also means we no longer
override styled_widget::impl_draw_background.

Do note I might use the design of the removed cache here to add some age functionality to the
font::pango_text cache.
