Don't decide if the button is pressed by the `buttons` bitmask, but rather by
event type. On macOS, the trackpad might produce a mousedown event with taps
instead of full clicks--if tapping is enabled in System Preferences--and in
this case might not set the flag in the bitmask.
Fixes#14640.
The Emscripten support for setting window icons introduced in #14490 does not work when using pthreads. Using `SetWindowIcon` will cause the program to crash. The reason for that is that the `Blob` constructor does not accept shared memory (`SharedArrayBuffer`).
We need to create a local copy of the icon data if necessary.
Same deal as the current Windows code: this "fixes" proximity but limits you
to a single pen device. But this is probably okay for most reasonable use
cases.
Now everything will attempt to track pens through proximity changes (instead
of removing the pen entirely). testpen.c has been updated to reflect this.
Some platforms and devices are better at this than others, but this seems like
a significant usability improvement across the board.
Fixes#12992.
This allows us to avoid browser mouse emulation for touches, since we provide
our own anyhow.
The other option is to "prevent default" in the legacy touch event handlers we
historically used, to tell the browser not to supply emulation, but we can't
currently tell Emscripten to mark those handlers as not "passive," so as it
stands they are unable to prevent default. Using Pointer Events bypasses this
problem entirely.
Fixes#13161.
The Module interface is the one used by the outside world. This code
is inside the module itself so can use the internal name, avoiding the
need to export this function on the Module at all.

According to the documentation and testing the `emscripten_webgl_create_context` function returns `0` on error as oppposed to a negative number. This was causing the error message to be empty when the later `emscripten_webgl_make_context_current` call fails given the invalid context.

Moved the event handlers from SDL_CreateWindow to SDL_VideoInit

* Allow custom message boxes with colors and multiple buttons to work if Asyncify is enabled
* Keep old functionality of using alert when Asyncify is not available
* Update testmessage to allow for setting random colors as the color scheme of the message box
Move hints used by Emscripten to window properties. This change will be necessary if multiple windows for Emscripten will be supported in the future.
- Added Window Create Property SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_CANVAS_ID
- Added Window Create Property SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_KEYBOARD_ELEMENT
- Use hint SDL_HINT_EMSCRIPTEN_CANVAS_SELECTOR as override to SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_CANVAS_ID
- Use hint SDL_HINT_EMSCRIPTEN_KEYBOARD_ELEMENT as override to SDL_PROP_WINDOW_CREATE_EMSCRIPTEN_KEYBOARD_ELEMENT
With ASAN enabled the existing code triggered null-pointer-dereference
in the strcmp since EMSCRIPTEN_EVENT_TARGET_WINDOW is a "fake" pointer
with the value ((const char*)2). In fixing this it was also noticed
that using the #window/#document/#screen targets as mentioned in the
docs fails since document.querySelector() returns null for them and we
should instead be mapping them to the special HTML targets provided.
This is just enough to delay MOUSE_LEAVE events until a drag ending outside
the canvas is released, and make sure the MOUSE_UP event has the canvas's
SDL_WindowID, which it wouldn't when mouse focus is was lost by this point.
Fixes#10033.
Any requested swap interval will be saved and set on the first PumpEvents.
Once PumpEvents has been called at least once, swap intervals are set
immediately.
This assumes that events won't be pumped until after an Emscripten main loop
has been defined, and so prevents a warning on the javascript console:
"emscripten_set_main_loop_timing: Cannot set timing mode for main loop since
a main loop does not exist! Call emscripten_set_main_loop first to set one
up."
Fixes#9969.
