Image2::scale and Image2::resize

[TaaTT4]

Why Image2::scale and Image2::resize methods are stripped out by an #ifdef 0? Do they not work?
I'm asking because, since we're working on sort of mini editor, it would be very useful to have those functions in play.

Image::scale needs porting, as it relies on PixelUtil instead of PixelFormatGpu
Additionaly, the scaling routines need to be checked to see if they properly support the case when bytesPerRow != bytesPerPixel * width

We assume a rowAlignment of 4 (the start of each row is aligned to 4 bytes) and that's why bytesPerRow may not match. Old Image did not have that restriction.

Pixel formats with a size of 4 or 8 bytes are naturally aligned, but that's not true for 8/16/48 bit images.

Note however, this is not a complex task. Anybody should be able to port it with relative ease. (I'm not interested and I'm focused on other stuff)

Cool! Can you put this feature even in v2-2-irradiance-field branch (since I've noticed that you mostly work on master branch)?

I'll be merging it once he puts it on the master branch.
