Subject: [SDL] Bug in GL_SWAP_CONTROL extension name.
The checked extension name is incorrect.
The attached patch fixes it to the correct name.
I don't think that under any setup, this extension name was ever
correct, which is why its not OR'd against the old check.
This fixes the "tear effect" (vsync problems) I had here with nVidia
GLX drivers.

The value returned by \fBSDL_JoystickGetAxis\fP is a signed integer (-32768 to 32768) representing the current position of the \fBaxis\fR, it maybe necessary to impose certain tolerances on these values to account for jitter\&. It is worth noting that some joysticks use axes 2 and 3 for extra buttons\&. .SH "RETURN VALUE" .PP Returns a 16-bit signed integer representing the current position of the \fBaxis\fR\&. .SH "EXAMPLES" .PP .PP .nf \f(CWSint16 x_move, y_move; SDL_Joystick *joy1; \&. \&. x_move=SDL_JoystickGetAxis(joy1, 0); y_move=SDL_JoystickGetAxis(joy1, 1);\fR .fi .PP .SH "SEE ALSO" .PP \fI\fBSDL_JoystickNumAxes\fP\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:00
