don't automatically create gaps if one already exists that can be resized
...
Rather than constantly create gaps, we can more intelligently determine whether
a gap can be extended to take the place of a block being removed, etc.

moved timeline undoable commands to using the new NodeAddCommand
...
Previous iteration used some "magic code" that added clips automatically to the
timeline. This was functional but ultimately outside of the undo commands'
control meaning nodes could be infinitely added and abandoned. This makes the
add process part of the undo command which means it's all undoable as the user
would expect.

allow gaps and transitions to be selected in the timeline
...
This will be useful for various reasons, however the behavior of selecting
gaps and transitions will need to be regulated harder than clips in the near
future.

...
Creating and destroying textures is a slow process, particularly when we can
re-use them throughout most of the render chain. We now keep them stored so
they can be re-used which improves performance substantially.

This was many changes that were largely fundamentally related. They included:
- More const modifiers to enforce read only node graphs
- Support for fragment and vertex shaders from the nodes
- Support for node code loaded externally (embedded into the binary)
- Fixed issue preventing two textures from being used in a shader
- Removed several unused functions and cleaned up code
- Fixed video media node misreading its matrix input
