From 9d7126c11b5f1577b00987b8d5f0f7f761b012d7 Mon Sep 17 00:00:00 2001 From: Simon Howard Date: Mon, 4 Jun 2007 18:32:50 +0000 Subject: Rename txt_main.c to txt_sdl.c; add txt_sdl.h for SDL-specific API functions, while keeping txt_main.h for the common API. Add TXT_SDL_SetEventCallback to allow programs to intercept SDL events in the textscreen main loop.
