Fixes

• Fixed tablet input problems by reverting the default input method to be Low Precision mode, the same as in 1.8.3. 
• Added tablet input preference (in Tools section) to opt-in to High Precision mode, or Windows Ink mode (previous command line options --legacy-wintab and --disable-wintab are now ignored).

[How to Edit the Alpha Channel]

I'm pretty sure this was working as expected, PS style, and got broken on one of latest versions.

It does make zero sense that all tools only adds white to the Alpha channel. It's like all operations are only additive.

[Preferences back/forth arrows]

this one is more of an annoiance than anything, but since it seems to me as something broken, I decided to post this here.

when you want to check all your preferences, like when starting with a software like Affinity's, I normally find that the back/forth arrow keys serve to jump between the several preferences pages. currently it works like a browser backwards/forwards which is not very helpful and for you to jump between all the pages means you have to use the dropdown everytime.

so when I'm in Colors, the back arrow would always go to General and the forward arrow would always go to Performance, following Preferences main page (and not its alphabetically sorted dropdown)...

thanks for these fantastic softwares!
