Using ImageData:setPixel for non rgba8 ImageData types

[lawrziepan]

Currently im using an imagedata object to store the state of a grid in my game, and the most convenient way for me to do this is by using the "r8" ImageData type. How do I use the setPixel method when it expects r, g, b and a parameters, but my ImageData object only needs an r argument? Thanks

It needs all the parameters and the underlying implementation ignores the superfluous ones if necessary.

Oh, thank you
