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.

Seems to be a regression in this commit: https://hg.libsdl.org/SDL/rev/7fdbffd47c0e
SDL_CalculatePitch() was using format->BytesPerPixel, now it uses SDL_BYTESPERPIXEL().
The underlying issue is that "surface->format->BytesPerPixel" is *not* always the same as SDL_BYTESPERPIXEL(format);
BytesPerPixel defined as format->BytesPerPixel = (bpp + 7) / 8;
vs
#define SDL_BYTESPERPIXEL(format) ... (format & 0xff)
Because of SDL_pixels.h format definitions, one is giving a BytesPP 1, the other 0.
Using (1 << 14) instead of 0x4000 might be clearer for the maintainer, but
it makes it harder to look up these flags when debugging an app. The value
has to be written once by one person, the has to be read by tons of people
over and over.
"This patch does the following:
* Instead of SDL_FillRects calling SDL_FillRect in a loop the opposite
happens -- SDL_FillRect (a specific case) calls SDL_FillRects (a general case)
with a count of 1
* The switch/case block is moved out of the loop -- it modifies the color
once and stores the fill routine in a pointer which is then used throughout
the loop"
Fixes Bugzilla #4674.
The 10 ms delay effectively caps input polling at 100 Hz and rendering
at 100 FPS if applications use these functions in their event loop. The
delay may also lead to dropped frames even at 60 FPS due if they are
unlucky enough to hit the delay and rendering takes longer than 6 ms.
fix building with Mesa 19.2
With Mesa 19.2 building fails with:
/include/GLES/gl.h:63:25: error: conflicting types for 'GLsizeiptr'
The same type is defined in include/SDL_opengl.h for OpenGL and the two
headers should not be included at the same time.
This was just never noticed because the same header guard '__gl_h_' was
used. This was changed in Mesa. The result is this error.
Fix this the same way GLES2 already handles this: Don't include the GLES
header when the OpenGL header was already included.
(https://hg.libsdl.org/SDL/rev/6a3670d6108d)
The X11 target sets mouse->last_x and last_y in EnterNotify and then calls
SDL_SendMouseMotion(), which throws away the new position because it matches
the mouse->last_x and last_y we just set, meaning that if the pointer is
in the window when it created, SDL_GetMouseState() will report a position of
0,0 until a MotionNotify event (the pointer moves) arrives and corrects the
mouse state.
Mostly fixes Bugzilla #1612.
The SDL_USE_LIBDBUS define is set inside SDL_debug.h, therefore the
circular dependency made it impossible for this feature to be enabled.
Instead, guard SDL_dbus.h based on the autoconf variable HAVE_DBUS_DBUS_H
Additionally, fix one of the rtkit comments. CAP_SYS_NICE isn't required
to achieve high priority. But there is some scheduler config that rtkit
needs the app to setup.
