So this is the best so far version:

Just one note, with the last version of DMD:
dmd -O -noboundscheck -inline -release pnoise.d
pnoise.d(42): Error: pure function
'pnoise.Noise2DContext.getGradients' cannot c
all impure function 'core.stdc.math.floor'
pnoise.d(43): Error: pure function
'pnoise.Noise2DContext.getGradients' cannot c
all impure function 'core.stdc.math.floor'

Sorry, I forgot this:
Beside the error above, which for now I'm using:
immutable float x0f = cast(int)x; //x.floor;
immutable float y0f = cast(int)y; //y.floor;
Just to compile, your version here is twice faster than the
original one.
