Discrete window resizing (snapping to full character sizes)

• I am on the latest Hyper.app version
• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: macOS Mojave v10.14.0
• Hyper.app version: 2.0.0 stable

• The issue is reproducible in vanilla Hyper.app: Is vanilla, except for HyperPower (which is installed but disabled).

Issue

With most terminals (except for Konsole, for some reason), when you resize the window it automatically snaps it to full character widths/heights. This makes resizing much easier, since you don't have to worry about getting it pixel-perfect.

Now, for full screen you obviously can't do that (the current margin behavior is perfect), but for normal resizing, would you consider implementing this behavior?

The issue does not name files, tests, or an entry point. Trace Hyper's normal window-resize handling first, then determine how terminal character dimensions are exposed and how fullscreen margins are distinguished; done means normal resizing snaps to full character widths and heights without changing fullscreen behavior.
