8babda2c20 egl: SDL_EGL_LoadLibaryOnly() shouldn't set _this->gl_config.driver_loaded = 1
This is handled in in the higher-level SDL_GL_LoadLibrary().

All uses of SDL_EGL_LoadLibrary (which calls the Only version) are just
target-specific wrappers for their own GL_LoadLibrary hook, with two
exceptions which now handle driver_loaded correctly (although it's
questionable if these init-if-no-one-did-it-correctly-already code blocks
should exist at all, fwiw).

Fixes Bugzilla #5190.

c0a875faff SDL_EGL_ChooseConfig: don't fall through if no matching format exists
On Raspberry Pi 3 via the VC4 driver in firmware KMS mode, none of the
found configs match the desired format, causing the function to fall through
without any config being selected.

Fix by first iterating over the found configs, and if no match exists,
don't exclude the non-matching configs. This should fix RPI3 and possibly other
targets without breaking targets that have a matching native format (such as RPI4).

389c8995d2 opengl: Allow SDL_GL_MakeCurrent() to accept a NULL window (thanks, Martin!).
This allows you to bind surfaceless contexts on a background thread to, for
example, load assets in a separate context, for platforms that have different
requirements about sharing surfaces, etc.

Martin's notes on the matter:

"Here's a patch that enables passing NULL windows to SDL_GL_MakeCurrent, if
the involved APIs allow it. Currently, this is only the case for EGL, and
even then only if some specific extensions are present (which they usually
are).

If "surfaceless" contexts are not supported, SDL_GL_MakeCurrent continues to
generate an error (albeit with a more specific error message than it used to),
so this should not break anything that wasn't broken before."

(Please see https://bugzilla.libsdl.org/show_bug.cgi?id=3695 for more
discussion.)

Fixes Bugzilla #3695.

90f9e8f8b6 egl: Don't use SDL_LoadFunction to get GL entry points on Emscripten.
This results in a dlsym() call, which causes Emscripten to panic if the game
wasn't explicitly built dlopen support. eglGetProcAddress works just fine on
this platform, so just let that codepath handle it.

3ecce84749 egl: adjust how we load symbols in SDL_EGL_GetProcAddress.
Use eglGetProcAddress for everything on EGL >= 1.5. Try SDL_LoadFunction first
for EGL <= 1.4 in case it's a core symbol, and as a fallback if
eglGetProcAddress fails. Finally, for EGL <= 1.4, fallback to
eglGetProcAddress to catch extensions not exported from the shared library.

(Maybe) Fixes Bugzilla #4794.

aeee424f65 Fixed bug 4349 - SDL_CreateWindow fails with KMS/DRM after upgrading Mesa to 18.2.3
Rainer Sabelka

After I did an upgrade of my arch Linux installation (resulting in an update of Mesa to version 18.2.3), all my SDL2 applications which use the KMS/DRM driver stopped working.
Reason: Creating a Window with SDL_CreateWindow failed because the call to EGL
eglCreateWindowSurface() returns an error "EGL_BAD_MATCH".
After investigating with the debugger I figured, that the configuration, which has been selected from the output of eglChooseConfig(), has an "EGL_NATIVE_VISUAL_ID" which does not match the "format" of the underlying gbm surface.

The attached patch fixes the problem. It does so, by mimicking Weston's behavior.
All configurations returned from eglChooseConfig() which have an visual_id different from the gbm format are discarded, and only from the remaining ones the "best" match is selected.

fe6828272a egl: Don't change context when deleting current.
If we change the current context behind the app's back, those tracking
the current context to minimize context changes are going to get
confused.

This brings the EGL backend in line with the GLX one.

003d491f86 Fixed bug 3724 - Allow Angle Static Link
Carlos

We would like to add a switch (define) that allows us to compile Angle statically with SDL. That is, getting rid of the OpenGL DLL. Usually you need OpenGL to be loaded dynamically as DLL because implementation is provided by the system but no need with Angle.

Only 2 files need modification and it shouldn't affect current behaivor:
include/SDL_egl.h and src/video/SDL_egl.c, as in here

https://github.com/native-toolkit/sdl/pull/10/files

The flag name could be SDL_VIDEO_STATIC_ANGLE (instead of NATIVE_TOOLKIT_STATIC_ANGLE) as discussed here https://github.com/native-toolkit/sdl/pull/10

We have tested this with both Windows and UWP, using NME engine (https://github.com/haxenme/nme).

96305832bc Fixed bug 3702 - Clear error messages of SDL_LoadObject for optional libraries
Simon Hug

Some code in SDL loads libraries with SDL_LoadObject to get more information or use newer APIs. SDL_LoadObject may fail, set an error message and SDL will continue with some fallback code. Since SDL will overwrite the error or exit the function with a return value that indicates success, the error form SDL_LoadObject for the optional stuff might as well be cleared right away.
