Peter	e39b650f4d	Only bitblt on damage. ... Also add an alternative for key handling, which does not work any better...	2023-02-19 10:03:55 -08:00
Peter	a722e01a4f	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).	2023-02-19 10:02:25 -08:00
Peter	8cf471bec9	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.	2023-02-19 10:00:21 -08:00
