cepl.camera provides a simple camera implementation that uses cepl's 'spaces' feature.
By passing the camera's space as a uniform to a cepl shader you get automatic upload of the matrix4 that describe the transforms between the spaces used.
It is available from https://github.com/cbaggers/cepl.camera/tree/release-quicklisp
Please use the release-quicklisp branch
