annotate src/video/win32/SDL_gdirender.c @ 4423:7953336267c2

Disable error checks for reset actuators and set autocenter. Reset actuators and set autocenter might not actually be supported on all implementations. We'll just disable error checking since they aren't critical to neither opening the joystick nor the haptic subsystem.
