(vars_of_window): Vwindow_pixel_scroll_increment is a new variable. * redisplay-output.c (redisplay_normalize_glyph_area): make sure the clip offset doesn't exceed the height we have available to show. * window.h (struct window): add top_yoffset and left_xoffset for pixel scrolling. (WINDOW_TEXT_TOP_CLIP): new macro. * window.c (window_scroll): add behaviour for pixel-scrolling of tall lines. What happens when you set window-pixel-scroll-increment to nil..? Jan
