SSAO works again. Unfortunately it's unavoidable to have it work without
explicit attenuation control (by using just max distance).

Also it now supports orthographic cameras properly. The maximum distance is
now defined in world space units so it should be slightly easier to understand
and uniform across perspective and orthographic cameras.

The optimizations can be generalized for orthographic cameras but the code is
more complex and the runtime advantage is questionable in that case
(in the end a matrix transform is 4 dot products which are not that terrible)
so commented out the code there for now.

Correct normal reconstruction with optimized formula.

This needed some adjustments from the formula I found on the article on
view space reconstruction, since OpenGL makes different assumptions about its
projection matrix.

SSAO does not work yet correctly under new model assumptions but we are going
to substitute with nice horizon based ambient occlusion.

Refactoring of SSAO code. Uses some optimizations but result is different
still test file here to help with debugging.

Normalize the depth to the -1.0 to 1.0 range as well.

Add shader files to the source tree. It helps by displaying them in the
IDE

Trim tool:

Support metastrips and multiple strips at once.

WIP support for meta trimming

Hook widget event to the lamp operator.

Hook calling widget to operator event system. Alpha alpha code still.
Transform/lamp still don't process those.

Store the active widget in the context. This allows us to first call the
widget handler if needed.

Arrow handler that does something useful (tm). However still not hooked
up to operators.

Dummy handler for arrows, take care of some allocation issues for
operators.

Add callbacks for operator initialization. Now a widget will directly
call an operator and have its own handlers for input.

No handlers implemented yet.

Classic fix linking of the widget library.
