Bounds check indexing into intermediate screen buffer
...
When building with -DCMAKE_BUILD_TYPE=Debug, we assert() that the
index into the intermediate screen buffer is in bounds.

Keep damage notification boundaries within the current screen
...
On startup, bitblt calls may be made for the original screen size
and if the new screen size is smaller than that, we must ensure
that damage notifications are contained within the new screen.
Move definition of min() so we can use it in sdl_notify_damage()

Fix "error: implicit declaration of function" from dspsubrs
...
Creates an sdldefs.h, declares a few more functions in sdl.c static,
and includes sdldefs.h in dspsubrs.c when necessary.

Add support for setting the mouse cursor. Not finished!
...
Currently this just allocates a new X cursor each time, should be
amended to cache the cursor, just like X does at the moment.

Also add an alternative for key handling, which does not work any better...

Change SDL backend to accelerated renderer, support pixel scaling.
...
Edit main.c, init_SDL(1600, 1024, 1) means lisp display size 1600x1024, pixel scaling 1.
Try init_SDL(800, 512, 2) or even init_SDL(608, 1023, 3).

Add prototypical SDL support.
...
Build with cmake. This will create a new backend (ldesdl).
- Resolution can only be set by editing the variables in sdl.c.
- Key repeat does not work.
- Still problems with keysyms that implicitly contain modifiers.
- The entire screen is bitblted onto the SDL display every frame.
Support keyboard, and work on mouse.
Kind of working...
Fix display resolution problems.
