Android: fat presses, vibrator, onscreen keyboard, keep-screen-on, console scaling, touch-based console scrolling, additional bindables.
Some memory leaks fixed.
latency with the nq protocol over loopback is much reduced.
Terrain: now mostly a property of a (q1 for now) bsp map, file format changed, glsl now built in, terrain editor builtin improved/changed, holes supported.

Android: fat presses, vibrator, onscreen keyboard, keep-screen-on, console scaling, touch-based console scrolling, additional bindables.
Some memory leaks fixed.
latency with the nq protocol over loopback is much reduced.
Terrain: now mostly a property of a (q1 for now) bsp map, file format changed, glsl now built in, terrain editor builtin improved/changed, holes supported.
