Summary: This patch adds support for key events for the "rewind" and "fast forward" media keys on the Amazon Fire TV remote control.
How to reproduce the problem: Run Android build of SDL2 application on the Amazon Fire TV (tested with "stick" version) and log key events.
Expected behaviour: Every key pressed on the Fire TV remote control should result in a corresponding key event (pressed/released).
Observed behaviour: Of the bottom row of buttons on the Fire TV remote control, only the "play/pause" (middle) button generates a key event, while the "rewind" (left) and "fast forward" (right) buttons to not generate any event at all.
The attached patch adds support for these two missing buttons/keys.
Note 1: Some missing definitions were added for the already existing key codes SDL_SCANCODE_APP1 and SDL_SCANCODE_APP2 (to keep up the correct order of enumerations / array positions when adding the two new key codes).
Note 2: Definitions in "scancodes_linux.h" and "scancodes_xfree86.h" (to also add support for these keys on other platforms) were added without testing. However, I was unable to find corresponding definitions for these two media keys for Windows and Mac OS X.
Note 3: I have also updated the (broken) link to the USB usage page standard PDF document (comment in "include/SDL_scancode.h").

In X11 the SDL error "Unknown touch device" can occur after which the application stops recognizing touch events. For a kiosk-type application this results in a hang as far as the user is concerned. This is reproducible on HP Z220/Z230/Z240 workstations by swapping USB cables for a while and it also occurs with no physical changes, probably due to USB device power management. A workaround is to make SDL re-enumerate the touch devices like it does at startup. A patch is attached.
This currently doesn't affect absolute motion, which would need to be implemented on each windowing system so the cursor matches the reported mouse coordinates.

Observed when resizing or moving a window in Windows 7.
Depending on how you resize/move your window
, you may receive none or a lot of SDL_WINDOWEVENT_EXPOSED events
, at the moment you release the mouse button.
Maybe add this event to an already existing list of overflow candidates ?
This allows an app to know when a set of drops are coming in a grouping of
some sort (for example, a user selected multiple files and dropped them all
on the window with a single drag), and when that set is complete.
This also adds a window ID to the drop events, so the app can determine to
which window a given drop was delivered. For application-level drops (for
example, you launched an app by dropping a file on its icon), the window ID
will be zero.
There are platforms it isn't implemented on (and currently can't be
implemented on!), and there's currently no way for an app to know this.
This shouldn't break ABI on apps that moved to a revision between 2.0.3 and
2.0.4.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
