The plan is to put in adjustment.c every piece of code that has to do with document positioning, either computing it from data on the document side, or talking to GTK. We want to have at our disposal functions to compute sizes and positions without having to ask for it to a GTK widget. The new functions are: - move page_calc_height_width to adjustment.c - add page_calc_position that rotates a position relative to a page according to the rotation settings. - add position_to_page_number that computes the number of a page sitting at a given position (given in document-relative coordinates) - add page_number_to_position that computes the position (in document relative coordinates) that will be placed at the center of the viewport. - add page_is_visible that checks whether the given page intersects the viewport.

Instead of guesstimating the values of the scrollbars adjustments after a change in zoom level, connect callbacks to the "changed" GtkAdjustment event (which is emitted when the bounds or page_size of the adjustment change, e.g. when the zoom level changes), and compute the new values from there. The previous adjustment values are tracked in zathura->ui.hadjustment and zathura->ui.vadjustment (and updated by signal handlers as well), so that the view's position can be maintained while zooming. cb_view_hadjustment_changed() centers the page horizontally if a "best-fit" or "width" zoom is being performed, or if "zoom-center" is true; otherwise, it keeps the view horizontally centered around the same area of the page. cb_view_vadjustment_changed() always keeps the view vertically centered around the same area of the page. Many thanks to Marwan Tanager for thoroughly reviewing the various stages of this patch, and actually coming up with a working solution. Signed-off-by:
