Modified Files:
src/conio/scale.c
Log Message:
Make a generic odd pointy scaler.

Since we have all odd numbers thanks to the pointy scaler, and we
have 2x thanks to xBR, we should now be able to build any integer
scaling from a combination of those two scalers.

This, of course, assumes you have enough CPU and RAM to actually
do the scaling you want... powers of two will likely be the worst
case for scaling.

Also, do pointy scaling before xBR.

Log Message:
On scale fail, but both buffers back in the pool

If do_scale ever failed, it would result in graphics buffers not
returning to the pool, resulting in them never being reused.

Screw it, if the compiler doesn't optimize it, just use more CPU.

At least the warnings are gone.

UBSan claims this is undefined behaviour...

I don't believe them, but I'll fix it anyway.
