- Move touch-handling code for "regular" touch joystick into separate file
- Add new touch-handling code for "keypad" touch joystick. This is a somewhat complex state-machine to determine
which key to press depending on a full keypad rosette.
- Adds a callback to vm.c to hook into keyboard read callback. Allows us to immediately queue the next key if the
keypad touch joystick is long-pressed for either axis or button keys.
- 'animation' was too constrained a name to what these do, so switch to the overloaded term 'node' ;-)
- Touch handling is no longer the sole purview of the touchjoy, (in prep for touchable HUD elements)
* Removes Linux-specific joystick handling
* Adds cross-platform GLUT joystick handling; Caveats:
- GLUT is not robust to joystick hot plugging like my old Linux-specific code was. (Fix should be made in the
GLUT driver and pushed upstream if we really care)
- Deprecated X11 renderer now can only use keypad joystick
* Use defines instead of magic numbers in a bunch of places
* Remove deprecated ii_keymaps and only use iie_keymaps
* Allow keypad corners for emulated joystick
* Deprecate "lazy" color modes
* Allow setting speaker sound volume
* Make Joystick code more generic (future support of touch input)
* Deprecate setting emulator mode (//e is ascendant)
