/* External function that takes one integer and splits it
 * into four gap values:
 *    - outer horizontal (oh)
 *    - outer vertical (ov)
 *    - inner horizontal (ih)
 *    - inner vertical (iv)
 *
 * Each value is represented as one byte with the uppermost
 * bit of each byte indicating whether or not to keep the
 * current value.
 *
 * Example:
 *
 *   10000000   10000000   00001111   00001111
 *   |          |          |          |
 *   + keep oh  + keep ov  + ih 15px  + iv 15px
 *
 * This gives an int of:
 *   10000000100000000000111100001111 = 2155876111
 *
 * Thus this command should set inner gaps to 15:
 *   xsetroot -name "fsignal:setgaps i 2155876111"
