I'm not confident this is a complete fix, but I'm not confident the current
 resamplers are really worth keeping at all, either.

Added API for rectangle drawing (as opposed to filling)
Added placeholder API functions for circles and ellipses ... I'm not sure whether these will stay.
Optimized software line drawing quite a bit.
Added support for Wu's anti-aliased line drawing, currently disabled by default.

Fixed crash in joystick handling code.  Newer 2.6 kernels add an additional 'resolution' field to input_absinfo.  Note that we don't use that structure since we want to have enough space for the values even when building with an older kernel.

The thread ID is an unsigned long so it can hold pthread_t so people can do naughty things with it.

I'm going to be adding additional useful thread API functions, but this should prevent crashes in people's existing code on 64-bit architectures.

The SDL_MouseMotionEvent struct has a field named "tilt" (currently marked "for
future use"), for tablet stylus tilt information.  However, one value is not
enough for this, as tilt is two-dimensional.  Reserving only one field for
future use is no good when you're going to need two, so there should be two
fields, tilt_x and tilt_y.

Patch to use stdlib.h with Open Watcom

features are used we use directly the include file as with GCC.
