Dear Maintainer,

I'm trying to run a SDL1.2 based app that uses a touchscreen for user input.

This app runs fine on Debian 7.11. On Debian 10.13 I get absolute garbage
events from the touchscreen.

It appears libsdl1.2debian does not have SDL_INPUT_TSLIB enabled so it does
not have tslib support. This is needed to handle the multi-touch events from
the touchscreen.

I downloaded the source for libsdl1.2 and configured/built it with tslib
support and my app then works properly with the touchscreen,

I suggest enabling the SDL_INPUT_TSLIB feature so that touchscreens can be
properly supported.
