Fixed crash if initialization of EGL failed but was tried again later. 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().

Fixed bug 5012 - KaiOS keycodes support pelya KaiOS is an OS for feature phones, with numeric keypad and non-touch screen, and typically 512 Mb RAM and 4 Gb flash. It is based on Firefox OS, all apps are made with HTML5 and Javascript. SDL can be cross-compiled using emscripten and packaged as native app. This patch adds support for star '*' and pound '#' keys on such phones to generate SDL events.

emscripten: keep track of pointer lock losses and maybe regrab pointer later. If an Emscripten app is in relative mouse mode and the user presses Escape (or whatever is appropriate), then the pointer lock is broken by the browser. This keeps track of those losses, and next time the user presses a mouse button down on the canvas, if the app is still meant to be in relative mouse mode, we will attempt to regrab the pointer. This makes it much more seamless for things like first-person shooters, and the app doesn't need any manual intervention.

Fixed bug 2293 - Precise scrolling events Martijn Courteaux I implemented precise scrolling events. I have been through all the folders in /src/video/[platform] to implement where possible. This works on OS X, but I can't speak for others. Build farm will figure that out, I guess. I think this patch should introduce precise scrolling on OS X, Wayland, Mir, Windows, Android, Nacl, Windows RT. The way I provide precise scrolling events is by adding two float fields to the SDL_MouseWheelScrollEvent datastructure, called "preciseX" and "preciseY". The old integer fields "x" and "y" are still present. The idea is that every platform specific code normalises the scroll amounts and forwards them to the SDL_SendMouseWheel function. It is this function that will now accumulate these (using a static variable, as I have seen how it was implemented in the Windows specific code) and once we hit a unit size, set the traditional integer "x" and "y" fields. I believe this is pretty solid way of doing it, although I'm not the expert here. There is also a fix in the patch for a typo recently introduced, that might need to be taken away by the time anybody merges this in. There is also a file in Nacl which I have stripped a horrible amount of trailing whitespaces. (Leave that part out if you want).

This keeps track of those losses, and next time the user presses a mouse button down on the canvas, if the app is still meant to be in relative mouse mode, we will attempt to regrab the pointer. This makes it much more seamless for things like first-person shooters, and the app doesn't need any manual intervention.

emscripten_set_mousemove_callback(data->canvas_id, NULL, 0, NULL);
Fixed crash if initialization of EGL failed but was tried again later. 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().
