Improve touchscreen GUI

Technical contact: ?

Our launcher/options GUI has been designed for keyboard/mouse input, and does
not work well in practice on modern touchscreen devices.

Since it is theme based, part of the problem can be resolved by using a custom
theme. However, our GUI code will need extensions to allow it to behave like a
proper touchscreen application.





Improve touchscreen support in engines

Technical contact: ?

The games supported by ScummVM were written for keyboard and/or mouse input.
This makes it tricky to play some of them on touchscreen devices.

A potential GSoC proposal could consist of an inventory of touchscreen-related
problems in a number of engines, together with proposal on how to fix them.

Generally scripts will not be modifiable since they are shipped with the games
we support, but engine code can of course be freely changed. This will make
this a lot harder for some engines than for others, depending on how
script-based the input handling is.
