LibGfx: Implement SmoothPixels scaling mode
If you wanted to upscale an image, you had two options: - use Nearest Neighbor: it's probably a good choice. The image stays sharp.. unless you aren't using integer scales. - use Bilinear blending, but this on the other hand, doesn't handle upscaling well. It just blurs everything. But what if we could take the best of both of them and make the image sharp on integers and just blur it a little when needed? Well, there's Smooth Pixels! This mode is similar to the Bilinear Blend, with the main difference is that the blend ratio is multiplied by the current scale, so the blur on corners can be only 1px wide. From my testing this mode doesn't handles downscaling as good as the Bilinear blending though.
