This allows for this kind of code in an application:
int monitorID = 1; // the second monitor!
SDL_SetWindowPosition(sdlWin,
SDL_WINDOWPOS_CENTERED_DISPLAY(monitorID),
SDL_WINDOWPOS_CENTERED_DISPLAY(monitorID));
Fixes Bugzilla #2849.
The callbacks used to receive the HTML events were not removed if the joystick
subsystem initialization failed or if the joystick subsystem was quit. Also, the
already connected joysticks were not deleted if the initialization failed later.
The needed header files are already included with SDL.h. Still including them in
the test programs is confusing because it somehow suggests they would be needed.
It's slightly faster than failing later, after a strchr() call, since this
will get called multiple times with a NULL string if the system totally
fails elsewhere.
This change integrates initialization settings for ANGLE/WinRT, as suggested in
MSOpenTech's latest ANGLE template-projects (for MSVC).
This should fix some OpenGL initialization issues on WinPhone 8.1 on ARM, and
on the 1st-generation Surface RT.
SDL_JOYDEVICEADDED events must contain the device index which is a value between
0 and the number of connected joysticks. The old implementation included a value
based on the instance id instead. It worked in some cases because the values are
similar initially. But after disconnecting joysticks this is no more the case
and the always increasing instance id becomes larger than number of joysticks.
Exit was broken since the main loop extraction needed for Emscripten support
because the former local but now global variables were not reset correctly.
Windows Phone does not appear to allow VSync to be turned off. Doing so appears
to either result in content not getting drawn (when the D3D debug runtime is
turned off), or forcing VSync back on and logging an error (when the D3D debug
runtime is turned on).
VSync had been getting turned on anyways, this change just notes such:
- via the WinRT README
- by always setting the SDL_RENDERER_PRESENTVSYNC flag when creating an
SDL_Renderer on Windows Phone

Here's a patch to make the 'testrelative' demo program more useful: it just makes the orange rectangle wrap around. Previously, the orange cursor would just disappear off screen if you move the mouse a lot in one direction, so it was hard to tell if relative mouse mode was still working.
- Don't create a temporary context first; this was probably due to Windows
needing one to get the address of wglCreateContextAttribsARB(), but that's
a unique quirk of WGL, and doesn't apply to glX. The glX spec explicitly says
you have to get a function pointer that works with any context from
glXGetProcAddress(), including when no context exists.
- Properly check for the GLX_ARB_create_context instead of just looking for a
non-NULL glXCreateContextAttribsARB()...some implementations, like Mesa,
never return NULL for function lookups (Mesa returns pointers into a jump
table that is filled out when the GL is initialized; since you can look up
functions before you have a valid context, it can't definitely say a function
isn't valid at that point).
Normally there's a 200 millisecond delay on all focus events in case there
was a vidmode change, now we note the last vidmode change and only impose this
delay if a change happened extremely recently.
Thanks to Epic Games for reporting this issue.

The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
