- ubb-vga.h (calloc_phys_vec), physmem.c: non-contiguous memory allocator (for now, without really considering any mapping to physical memory) - Makefile (OBJS): added physmem.o - ubb-vga.h (grabfb), grabfb.c (grabfb): API change for non-contiguous frame buffer - ubb-vga.h (ppmimg), ppmimg.c (convert, ppmimg): API change for non-contiguous frame buffer - ubb-vga.h (tstimg), tstimg.c (pixel, color_bars, grill, grid, sides, dot, line45, arc, printc, text, ctext, tstimg): API change for non-contiguous frame buffer - tstimg.c (tstimg): we no longer need to clear the frame buffer - ubb-vga.c (frame, session, main): use a vector of line buffers instead of a contiguous frame buffer
