Support in Sharp for pixelwise arithmetic operations

[zigabostner]

Pixelwise arithmetic operations currently don't seem to be provided through the Sharp API even though libvips does implement them. Is this correct? Is there maybe any intention or plan to expose these operations also through Sharp at some point?

Does the linear() operation, which allows for pixel arithmetic, provide what you need?

If not, was there a specific operation you were looking for?

[zigabostner]

Ideally, I would like to be able to use the following operations: (from https://www.libvips.org/API/current/libvips-arithmetic.html)

vips_add
vips_subtract
vips_multiply
vips_divide
vips_sign
vips_sin
vips_cos
vips_atan2
vips_pow
vips_relational
vips_relational_const

Thanks, I'll tag this as a future possible enhancement.
