subset spatial 'mask' parameter shouldn't have resource selection enabled

[JanisGailis]

subset_spatial operation has a mask parameter which takes a Bool value to determine weather the output should be masked with the given region, or if the output should be cropped only to the bounding box of the given region.

In the operation invocation dialog this value has resource selection enabled leading to confusion - it can be understood that this is where the masking polygon should be provided:

By default the value selection switch is set to 'value' selection. It only gets automatically set to 'resource' selection in a very specific scenario:

A GeoDataFrame region is read in and selected, the subset_spatial is then invoked through right-clicking on a region (any) on the map and selecting subset_spatial from the context menu.

@JanisGailis Actually it should be ds that should receive the resource reference in this scenario, not mask. The code for this in TypeScript in the GUI, do you want to fix it on your own?

[JanisGailis]

I quickly looked at it, but couldn't understand how to fix it properly. I think the problem is that the bool type can theoretically be whatever, so all resources correspond to that type and the box gets populated. So, the proper fix would be to make sure that only resources of actual type 'bool' get added to the resource list.

EDIT: Ah, yes and that this only happens when the operation dialog is invoked through the right-click context menu when clicking on a shape that is a resource.

Assign it to me or Hans, if you prefer.

[JanisGailis]

Re-assign to Hans if needed. It would've been nice to take a shot at fixing this, but I guess my time is better spent working on operations.

I agree, see #733
