Otherwise, if we destroyed a different renderer, next time this one draws,
it'll clear errors forever (GL_INVALID_OPERATION for having no current
context, at least on Windows), hanging up the program in an infinite loop.
Fixes Bugzilla #1775.

SDL_RenderSetClipRect() calls into renderer->UpdateClipRect(renderer).
I am not sure if UpdateClipRect() can point to a number of clip rect update functions, but on my platform it calls D3D_UpdateClipRect().
In that function, the rect to pass to IDirect3DDevice9_SetScissorRect() has it's right field set as:
r.right = rect->w + rect->w;
But actually, this should be:
r.right = rect->x + rect->w;
This wanted an EGLint*, not a VisualID* cast to an EGLint*.
Without this, 64-bit X11 fails here, because the datatype sizes are different.
Fixes Bugzilla 1686.
This fixes bug #1446. You can now create a window with SDL_CreateWindow(...,
SDL_WINDOW_MINIMIZED), and not have it immediately restore itself.
It also changes SDL_RaiseWindow() to be a no-op on minimized or hidden windows,
which is how it behaves on Windows.
This looks like the rest of the code doesn't deal with windows, and probably
just deals with a single fullscreen GLES context, like a console would, so
making setwindowgrab a no-op makes sense in this case; it's already "grabbed."
Fixes Bugzilla #1850.
This is good policy, so it doesn't have a chance to leave it hidden on targets
that wouldn't necessarily reset it by default, but it also fixes a crash if
you try to use a message box after SDL_Quit() is called.
Fixes Bugzilla #1969.
It now tries to make sure the hardware can support a given format, and if it
can't, it carries on to the next best format instead of failing completely.

Cocoa_ShowMessageBox() ignores the "window" field of SDL_MessageBoxData, which means you can't assign a parent window to a message box. This is particularly egregious on Mac OS X, because it'll actually make the NSAlert visually part of the parent window instead of just concerning itself with window focus.

SetupWindowData in SDL_windowswindow.c doesn't initialize two members of SDL_WindowData with NULL. This is an issue because other parts of the SDL code seem to make the assumption that this is the case. WIN_DestroyWindowFramebuffer for example uses data->mdc and data->hbm if they're not NULL.

SDL_CreateTexture() is succeeding (i.e. returning a valid pointer) when the requested horizontal or vertical size of the texture exceeds the maximum allowed by the render. This results in hard-to-understand errors showing up when later attempting to use that texture (such as with SDL_SetRenderTarget()).
