Fixed a case where partial trigger pull could be bound to another button
There is a fundamental problem not resolved by this commit:
Some controllers have axes (triggers, pedals, etc.) that don't start at zero, but we're guaranteed that if we get a value that it's correct. For these controllers, the current code works, where we take the first value we get and use that as the zero point and generate axis motion starting from that point on.
Other controllers have digital axes (D-pad) that assume a zero starting point, and the first value we get is the min or max axis value when the D-pad is moved. For these controllers, the current code thinks that the zero point is the axis value after the D-pad motion and this doesn't work.
My hypothesis is that the first class of devices is more common and that we should solve for that, and add an exception to SDL_JoystickAxesCenteredAtZero() as needed for the second class of devices.
These are test programs for the SDL library:
checkkeys Watch the key events to check the keyboard
loopwave Audio test -- loop playing a WAV file
loopwavequeue Audio test -- loop playing a WAV file with SDL_QueueAudio
testaudioinfo Lists audio device capabilities
testerror Tests multi-threaded error handling
testfile Tests RWops layer
testgl2 A very simple example of using OpenGL with SDL
testiconv Tests international string conversion
testjoystick List joysticks and watch joystick events
testkeys List the available keyboard keys
testloadso Tests the loadable library layer
testlock Hacked up test of multi-threading and locking
testmultiaudio Tests using several audio devices
testoverlay2 Tests the overlay flickering/scaling during playback.
testplatform Tests types, endianness and cpu capabilities
testsem Tests SDL's semaphore implementation
testshape Tests shaped windows
testsprite2 Example of fast sprite movement on the screen
testthread Hacked up test of multi-threading
testtimer Test the timer facilities
testver Check the version and dynamic loading and endianness
testwm2 Test window manager -- title, icon, events
torturethread Simple test for thread creation/destruction
controllermap Useful to generate Game Controller API compatible maps
