[fpc-pascal] fpcanvas and Interpolation filters

[Graeme Geldenhuys]

Hi,

Looking at the 'fpcanvas' unit in FCL it seems we only have the
Mitchel Interpolation implemented.  Is this a correct assumption?

What about a few other types?
    'Box' aka "Nearest Neighbour"
    'Triangle' aka "Linear" or "Bilinear"
    'Hermite'
    'Bell'
    'B-Spline'
    'Lanczos3'

I have some pascal implementations for the others and if they are not
part of FCL already, I can always create a patch to add them.  Would
this be a worthy effort?

Regards,
