<pre>The best human visual acuity is ~1' (1 arc-minute = 1°/60).
Pixels of your 13" screen are 90 µm wide. To be discernable, a human without special bionic eyes -- that is to say most of them -- have to watch the
screen at a distance smaller or equal to 20 cm. Besides that, the closest viewing distance for a human that is not nearsighted is ~25 cm. This is a
tiring distance making headaches, but a possible one.
Using such a screen at such a resolution is meaningless, unless being heavily nearsighted, or bionic-sighted.
Now, you can use a wider screen fed by the HDMI or SVGA output of the graphic card. For instance, with a 65" screen, you will have to stand at a
distance of 1 m or less to get full benefice of your screen. This is not a matter of applications, nor of windows managers, but a matter of physics
and biology.
I do not see the point about adapting all applications to a meaningless situation or hardware tuning. The only point that could be interesting would
be to use an operating system automatically tunning the actual output format of the graphical card according to the actual size of the main screen
used, assuming a reasonable working distance of -- say -- 60 cm.
If you want to use your 13" screen, just downgrade the actual working resolution of your graphic card, and all applications will be ok without
expecting meaningless modified releases.
Or just buy another screen wide enough, and keep the full resolution without working too far from it.
Expecting from Scilab or any other application to adapt to your screen is a rather a non-sense. Even if it is implemented through Preferences for
fonts sizes, it will not enlarge curves thicknesses, and you will get blinking graphics.
Moreover, you will have to apply this kind of tuning for each of your applications. Just do it only once on your PC, and that's it.
