Fix bug #14567 with jumpy scrolling of tall images.

 src/xdisp.c (Fline_pixel_height): New function, required for solving
 bug #14567.

 lisp/simple.el (line-move-partial): Don't jump to the next screen
 line as soon as it becomes visible.  Instead, continue enlarging
 the vscroll until the portion of a tall screen line that's left on
 display is about the height of the frame's default font.
