Minor rendering cleanup
...
Remove the x/y parameters from the rectangle primitive. They're always zero
since we always render with a transformation
matrix.

Fix GL context state handling
...
Make our GL context not current when done with the initialization
and make it current for the duration fo primitive creation and frame
rendering.
Fixes #4

Prepare for caching rendering info for Items
...
Replace the RenderTree with a RenderingCache that is just the free-list vector
of rendering primitives.

Simplify geometry handing
...
Replace the use of kurbo's primitives with lyon/euclid. This means less data copying,
conversion and also no annoying precision
casts.

Add primitive rectangle rendering

This is still uncached, but gets something onto the screen.

Get rid of the glutin dependency in the GL renderer -- the caller is now responsible for swapping buffers.

Some work towards implementing the gl renderer

... in plain GL(ow). swapbuffers and clearing the color buffer is working.

Use cgmath throughout

And remove usage of kurbo::Affine. That avoids extra translations.

Start with image rendering
...
These are the basics. Still to do are fixing the alpha channel blending, the rect handling,
a texture type to avoid consuming the image over and over again. And more :-)

Split graphics::RenderNode into RenderNodeMut and RenderNode

This allows a read-only tree traversal and thus rendering.

First implementation of a tree of rendering nodes
...
The idea is that they can be recursively rendered and propagate at least
the transform but also clip in the future.
One thing that's left is to split RenderNode into RenderNode and
RenderNodeMut, so that the rendering itself can be done on a non-mutable
tree reference.
