[Scummvm-devel] New OS interface

[Marcus Comstedt]

Looking at sdl.cpp to figure out the new mouse interface, I see

        const int ydraw = _ms_cur.y + _current_shake_pos - _ms_hotspot_x;
        const int xdraw = _ms_cur.x - _ms_hotspot_y;

Is this the correct semantics?  Should -hotspot_x really be added to
y, and -hotspot_y to x?  Seems a little backwards (or rotated 90° at
least :)...

Also, I'm a little curious about

        // Create a thread
        virtual void *create_thread(ThreadProc *proc, void *param) = 0;

Fortunately it seems that this function is never called, but it still
worries me a little.  I have no intention of writing a preemptive
thread implementation for the Dreamcast.  If something needs to be
done in the background I'd rather do it from a raster or timer
interrupt, if calling it from delay_msecs is insufficient.
