The render viewport is automatically re-centered when the window changes size, so applications that don't care will not have to handle recalculating their rendering coordinates.

Fixed API for drawing and filling multiple rectangles - the parameter should be an array of rects, not an array of pointers to rects.

Fixed API for updating window rects for consistency with other APIs - the order is pointer to array followed by count in array.

There's a new event that's always sent when the window changes size, and that event is what the renderers listen for to determine if they need to rebind their context.

Added a way to get a framebuffer interface for a window, and also a way to create a software renderer for an arbitrary surface.
The software renderer has been re-routed to use the framebuffer interface, which makes it possible to have software rendering available even on simple ports.

This allows me to reduce the set of formats supported by the renderers to the most optimal set, for a nice speed boost.

Moved the rendering code out to a separate directory in the hope that it can someday be completely decoupled from the rest of the library and be expanded to an awesome 2D on 3D library.

The rendering functions take a context so it's clear what window they're drawing to.  This also potentially opens to the door to multi-threaded rendering in the future.

Making the API simpler, the renderer present semantics are always having a backbuffer and then discarding it.  This is best for hardware accelerated rendering.

Making the API simpler, scaling is always defined as linear interpolation and should be supported as much as possible on all renderers.
