This is an UNSTABLE release. This version significantly rewrites code to predict reflection position and integrate them, especially in case of rotation crystallography. If things go wrong with analysis, it is better to revert to 1.0.0-rc.123. * jfjoch_broker: Improve refection position prediction and Bragg integration code. * jfjoch_broker: Align with XDS way of calculating Lorentz correction and general notation. * jfjoch_writer: Fix saving mosaicity properly in HDF5 file. * jfjoch_viewer: Introduce high-dynamic range mode for images * jfjoch_viewer: Ctrl+mouse wheel has exponential change in foreground (+/-15%) * jfjoch_viewer: Zoom-in numbers have better readability Reviewed-on: #31 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch> Co-committed-by: Filip Leonarski <filip.leonarski@psi.ch>
