Note that I tried to keep this patch minimal but I think we should move IntegerConversionConfiguration to be a template parameter instead since all the call sites know the configuration at compile time and this would optimize out the branches.

EFL build is failing, maybe because of a difference in the version of gcc it’s using?

Why no use of this new feature in any IDL file yet?

Often, inlining and constant folding is enough to optimize out the branches. So maybe we don’t have to do that.

[Clamp] is used in our IDL although not a lot at the moment.

Well, but only 2 of them are inlined in the header. All of the others are in the cpp.
