Fixed bug #220 The AltiVec blitters don't compile, since they require __VEC__ to be enabled in order for the compiler to understand "vector" and friends (i.e. do AltiVec) But you don't want to turn AltiVec on globally, since then the code would only run on a G4 (there are already runtime tests, before using the AltiVec variants) The solution here is to enable AltiVec locally, for the actual AltiVec code.

32 Simply put, a \fBSDL_MOUSEMOTION\fP type event occurs when a user moves the mouse within the application window or when \fI\fBSDL_WarpMouse\fP\fR is called\&. Both the absolute (\fBx\fR and \fBy\fR) and relative (\fBxrel\fR and \fByrel\fR) coordinates are reported along with the current button states (\fBstate\fR)\&. The button state can be interpreted using the \fBSDL_BUTTON\fP macro (see \fI\fBSDL_GetMouseState\fP\fR)\&.

34 If the cursor is hidden (\fI\fBSDL_ShowCursor\fP(0)\fR) and the input is grabbed (\fI\fBSDL_WM_GrabInput\fP(SDL_GRAB_ON)\fR), then the mouse will give relative motion events even when the cursor reaches the edge fo the screen\&. This is currently only implemented on Windows and Linux/Unix-a-likes\&.
