Fix T101969: Crash when using large texture with nonstandard colorspace 

When the image colorspace is not data, linear or sRGB, the image will
be converted to float (and colorspace-converted) during loading.

However, if it also needs to be rescaled (due to exceeding the GPU
texture size limit), the resizing assumed that it's still a byte
texture.
