Description
the pixel sizes we have available are 1x1, 1x2, 2x1, 2x2, 3x3, 4x2, 2x4 and 4x4 - would be great if it would be like [textfield]x[textfield] (just like "Width:[textfield] Height: [textfield]" above there), and would be great if [textfield]x[textfield] could accept floating-point values, so we could have aspect-ratio available (just like we have available on gimp) like [2.844]x[2] (this would look like a colecovision or master-system on a pal cinescope display)
and there is a bug (or misfeature) that would be great having fixed: normally when we work on smaller picture sizes, the picture seems always placed on the upper-left edge over a black background, and i guess that this would be optional, since i would prefer to have it centered over a grey background, and some people would want to have it in an even different way
would be great also if the [clr] button would clear the display using the selected background colour, not black

it doesn’t need anti-aliasing - it would look like "-aspect" from mame/mess command-line in sdl mode, using 2.844x2 we would have some 2x2 pixels and some 3x2 pixels, depending on where they are - the useful of this is also enabling us to use drawing tablets on the desired aspect ratio, without having to concern with losses resulting from constant resizing - the resulting "ugliness" would be some kind of "compromise" we wouldn’t mind that much for that, the important would be having that available

I would prefer to keep integer ratios only. If you need stranger ratios, you will need to get a retina display and use 8x6 or some other large numbers.
The clr button clears with the background color, if you right click it. Read the helpfiles!

In the SDL2 branch, the rendering engine is able to zoom at arbitrary (integer) sizes. I just checked on a 95dpi screen : 4x5 pixels look very much like VGA mode, :)
Non-integer sizes can't work well : if I display with linear interpolation, you lose pixel precision, ie. a pure black-and-white image will show many grey pixels; or I display nearest neighbor, and then the "volume" of pixels is not constant, which is just too ugly.
