The swcursor used a 32x32 image for saving/restoring screen contents for no reason. Add a doflush argument to swcursorhide(), so that disabling software cursor with a double buffered softscreen is properly hidden. The doflush parameter should be set to 0 in all other cases as swcursordraw() will flushes both (current and previours) locations. Make sure swcursorinit() and swcursorhide() clear the visibility flag, even when gscreen is nil. Remove the cursor locking and just do everything within the drawlock. All cursor functions such as curson(), cursoff() and setcursor() will be called drawlock locked. This also means &cursor can be read. Fix devmouse cursor reads and writes. We now have the global cursor variable that is only modified under the drawlock. So copy under drawlock. Move the pc software cursor implementation into vgasoft driver, so screen.c does not need to handle it as a special case. Remove unused functions such as drawhasclients(). |
