Problem statement
- Choosing a channel in the histogram dialog requires two clicks: opening a combo box, then choosing a channel.
- The info section of the dialog isn't always necessary, but takes precious vertical space.
- Versions 2.9.x and 2.10 make the histogram dialog design even busier by introducing linear/gamma-corrected switch that has no obvious on/off state (at least, with some UI themes).
Better solutions can be devised, as seen in other software (see 'Tentative design' section).
What should be available
On-canvas switches (for the histogram area): RGB, R, G, B, Value or L*, Linear/Log scale, Linear Light / Gamma-Corrected space
TODO: We need to decide if we should expose color channels from other color spaces such as CIE LCH. We already expose LCH channels in color selection tools, and exposing LAB / LCH in e.g. Curves tool/filter makes a lot of sense, so this needs a decision.
TODO: Do we stick with Value or go for L*?
TODO: RGB, R, G, and B are mutually exclusive on display. Should GIMP be able to display either of them along with Value or L*?
