message: glterm: cleanup
diff: // - [x] proper glterm termination (window close as well as process exit)
  // - [x] input: rename Numpad_Dot to Numpad_Decimal, and others (Div -> Divide, etc)
  // - [x] Fix window-resize: call Screen::resize(), PseudoTerminal::updateWindowSize()
  +// - [ ] logging: runtime-configurable logging (to file or stdout)
  // - [ ] Fullscreen support (ALT+ENTER, or similar)
  // - [ ] other SGRs (bold, italic, etc)
  // - [ ] fix text positioning (chars seem pressed down instead of centered)
