- Enables choosing touch keyboard or touch joystick
- Enables increasing/decreasing speed
- Enables opening main popup menu
- Also migrates all gesture responsibility away from Java side of things
- '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)
- menu/HUD creation functions moved to better location and renamed
- CPU change animation now default displays on desktop Linux (exercise common HUD codepaths with mobile)
CPU speed animation touch-ups, and enable building for desktop
Rename/shuffle animation declarations and code
Refactor backend video system to be a dynamically initialized module
Basic CPU speed texture animation works on desktop Linux and Android
Use static pixel buffers to avoid malloc/free churn
Improve CPU animations
First cut at CPU speed message animation
Refactor some of the classic interface functions to be potentially reusable elsewhere
* previously this classic interface acted as an oldschool modal dialog (which worked fine with the X11 renderer
where we actively pumped the event loop)
* Merges input handling into one routine called thru video_sync at refresh rate
* Adds keypad joystick calibration routine
* Simplify joystick calibration routines to use same codepath as main emulator joystick handling
