Reworked the aspect function. Now we calculate the display aspect from the pixel width and

pixel height (and not from the physical size, which was the root cause for rounding errors).
Cropping calculation is reworking, now the rounding is correct. I introduce a new aspect mode
"original" which displays the output with the original size (but after correction the
pixel aspect ratio). Tested with vaapi(X11) and vaapi(DRM) with and without libplacebo.

Beginners Guide for libplacebo:
-------------------------------
When using libplacebo you will find several config options.
When using libplacebo you will find several config options.
First of all you need to set the right scaler for each resolution:
Best you beginn with setting all to "bilinear". If that works ok for you, you can try to change them
for more advanced scaler. I use ewa_robidouxsharp on my GTX1050, but your mileage may vary.

Unfortunatly on INTEL not all scalers may work or crash.

Then you should set the Monitor Colorspace to "sRGB". This guarantees you the best colors on your screen.
