Screen ratio issue and image size

[Melvovin]

I have two issues:
The first one is that when I set a screen resolution in canvas using:
canvas = FullScreenCanvas.GetFullScreenCanvas(new Mode(columns, rows, colorDepth));
I can't set the resolution to a ratio other than 4:3 for resolutions like 1280x720 or 1920x1080
It shows this error:

The other issue is that I can't find a method to change a Bitmap's size at runtime, including downscaling it and changing the width and height differently.

Pretty sure I saw someone say that the resolutions must be supported by the video card or something like that. Basically how you can't have a resolution of 10x10 in Windows. (#3197)

Also I do think I saw a method to scale a bitmap somewhere, I'm gonna look for it in docs.
