tone equalizer: displayed exposure mask affected by iops coming later in the pipeline

[flannelhead]

Describe the bug
When tone equalizer is enabled and "display exposure mask" is on, iops coming later in the pipeline affect the displayed exposure mask.

To Reproduce
Steps to reproduce the behavior:

1. Enable e.g. Filmic RGB with some added contrast
2. Enable tone equalizer and click "display exposure mask"
3. Ensure tone equalizer comes before Filmic RGB in the pipeline
4. Disable and enable Filmic RGB and observe that the displayed exposure mask changes. Note that the displayed histogram on tone equalizer's "advanced" tab fortunately doesn't change, nor do the values displayed under the cursor when hovering the mask.

Expected behavior
The displayed exposure mask should not change due when enabling or disabling Filmic RGB (or any other module coming later in the pipeline). The dependency on later modules makes it hard to assess the effect of the tone equalizer masking settings.

Screenshots
If applicable, add screenshots to help explain your problem.

Platform (please complete the following information):

• OS: Arch Linux x86_64
• Version be6a924

Additional context
@aurelienpierre: what's your suggested workflow with filmic and tone equalizer like? Do you first tune tone equalizer and only then enable filmic rgb and any other iops later in the pipeline? This kind of workflow would work around this problem, but I would still appreciate if I could revisit tuning the tone equalizer mask later without disabling the other modules. I think I'll spend some quality time watching your awesome tutorial videos this weekend anyway :)

Given how the current pipeline is wired, I'm afraid I have no other option. Either I use the image output, with later modules applied on, or the mask preview, possibly interfering with parametric/drawn blending elsewhere. Notice it's the same issue with the retouch module.

I suppose this issue may be closed unless someone else thinks the behaviour should be changed. Personally I'm fine with the current behaviour and will adjust the mask before applying any modules further along the pipeline. :)

Ok, closing.
