[DIGImend-users] Setting pressure sensitivity curve?

[<co+...@io...>]

Hello.

I recently obtained a Huion H420. I'm using Arch Linux and am currently
at kernel version 4.7.6-1-ARCH.

I got the tablet, plugged it in, and it magically worked. Because there
was no configuration, I'm working under the assumption that I *am*
actually using the drivers that DIGImend have created (nice work, if
so!).

When I plug the tablet in, the following lines are logged in dmesg:

My problem: There don't appear to be any tools available for
configuring the pressure sensitivity curve. The programs I use (GIMP,
Krita, Blender) have varying degrees of support for configuring custom
curves. In the case of Blender, there just isn't any ability to
configure anything, and the pressure sensitivity curve is far too
severe. It goes from maximum pressure when painting to very little
pressure in just a few very noticeable steps.

Is there a tool I can use to configure things system-wide, or are
applications expected to provide everything on Linux?
