size is defined as columns in horizontal spacing commands and lines
in vertical spacing commands. Actual column widths and line heights
are set by control functions or are taken from the currently selected
font.

parameters of the following sequences:
▪ HPA, HPB, HPR
▪ VPA, VPB, CUU
▪ VPR, DECSHTS, DECSVTS
▪ DECSLPP, DECSTBM, DECSLRM
