Description

While writing a simple image viewer, I discovered that scaling down is not supported. That is, if the pixel buffer is larger than the surface texture. Would it be difficult to scale an image to fit the surface texture, adding borders horizontally or vertically as appropriate to keep the aspect ratio?

Contributor guide

Research direction
Investigate how the pixels library renders textures and implement scaling down with aspect ratio preservation. Use bilinear interpolation or nearest neighbor for scaling, and add border padding to fit the surface texture size.
