English Amiga Board - View Single Post - sharp-bilinear-simple shader for FS-UAE

I think, I found a bug.

RTG screen 960x540 should sharp-scale to 1920x1080 (same output as texture_filter=nearest) but it does not.
It looks like only bilinear scaling is used, same result as no-shader + texture_filter=bilinear.

Edit: Changed

floor(rubyOutputSize / rubyInputSize)

to

floor((rubyOutputSize + 1.0) / rubyInputSize)

to "save" one pixel.
I have absolutely no clue what I'm doing here, but it seems to work, LOL
