Fix tomo tiling histogram and focus on ROI
Two fixes:
- Avoid focus on ROI on chrome: closes "Weird black strock around selected ROI on chrome" daiquiri-tomo#172 (closed)
- Request the server to convert
int64
to a safely handled type: There has been a change inh5grove
which used to do the cast by default and has to be explicitly asked now. related to "TIling: Histogram not properly displayed" daiquiri-tomo#207
For the 2nd issue, the other option is to use big ints, but it requires either conversion in the frontend (but simpler to use the backend which already supports it) or update of h5web to support it? attn @bocciare @loic.huder
