This is an UNSTABLE release. * jfjoch_broker: Add auto-contrast option for preview images * Frontend: Add logo image * jfjoch_viewer: Add logo image * jfjoch_viewer: For image chart allow to set min value to zero * jfjoch_viewer: For resolution estimation plots, visualization uses 1/d^2 as measure * jfjoch_viewer: Add 3D unit cell visualization (experimental/WIP/not really there) * Documentation: Add logo image Reviewed-on: #16 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch> Co-committed-by: Filip Leonarski <filip.leonarski@psi.ch>
