/* Return the pixel width/height of frame F if it has
     COLS columns/LINES rows.  */

#define FRAME_TEXT_COLS_TO_PIXEL_WIDTH(f, cols) \
    (FRAME_COL_TO_PIXEL_X (f, cols) \
     + (f)->scroll_bar_actual_width \
     + FRAME_TOTAL_FRINGE_WIDTH (f)      \
     + FRAME_INTERNAL_BORDER_WIDTH (f))

#define FRAME_TEXT_LINES_TO_PIXEL_HEIGHT(f, lines) \
    (FRAME_LINE_TO_PIXEL_Y (f, lines) \
     + FRAME_INTERNAL_BORDER_WIDTH (f))


and

#define FRAME_INTERNAL_BORDER_WIDTH(F) ((F)->internal_border_width)

But the internal border is on two sides, so it should be
2*FRAME_INTERNAL_BORDER_WIDTH (f).

FRAME_COL_TO_PIXEL_X and FRAME_LINE_TO_PIXEL_Y include the left and
top side internal border width, respectively.  So, the internal border
is already counted twice in FRAME_TEXT_COLS_TO_PIXEL_WIDTH and
FRAME_TEXT_LINES_TO_PIXEL_HEIGHT above.

Thanks for the clarification. One pixel is still missing though, I'll keep looking.
