I propose horizontal movement.

No, it should be configurable. Perhaps environment variable
or a rc file (of GTK?). Environment variable would be better as
a quick standard.

  setenv KNOBS_CONTROLLED_HORIZONTALLY
  setenv KNOBS_CONTROLLED_VERTICALLY
  unsetenv KNOBS_CONTROLLED_HORIZONTALLY
  unsetenv KNOBS_CONTROLLED_VERTICALLY

  #include <stdlib.h>
  if (getenv("KNOBS_CONTROLLED_HORIZONTALLY") != NULL) {
    // Horizontal movement.
  }
  if (getenv("KNOBS_CONTROLLED_VERTICALLY") != NULL) {
    // Vertical movement.
  }
