Further frame-geometry cleanups
-------------------- ChangeLog entries follow: --------------------
man/ChangeLog addition:
2010-03-03 Ben Wing <ben@xemacs.org>
* internals/internals.texi (Intro to Window and Frame Geometry):
* internals/internals.texi (The Paned Area):
* internals/internals.texi (The Displayable Area):
Update to make note of e.g. the fact that the bottom gutter is
actually above the minibuffer.
src/ChangeLog addition:
2010-03-03 Ben Wing <ben@xemacs.org>
* emacs.c:
* emacs.c (assert_equal_failed):
* lisp.h:
* lisp.h (assert_equal):
New fun assert_equal, asserting that two values == each other, and
printing out both values upon failure.
* frame-gtk.c (gtk_initialize_frame_size):
* frame-impl.h:
* frame-impl.h (FRAME_TOP_INTERNAL_BORDER_START):
* frame-impl.h (FRAME_BOTTOM_INTERNAL_BORDER_START):
* frame-impl.h (FRAME_LEFT_INTERNAL_BORDER_START):
* frame-impl.h (FRAME_PANED_TOP_EDGE):
* frame-impl.h (FRAME_NONPANED_SIZE):
* frame-x.c (x_initialize_frame_size):
* frame.c:
* gutter.c (get_gutter_coords):
* gutter.c (calculate_gutter_size):
* gutter.h:
* gutter.h (WINDOW_REAL_TOP_GUTTER_BOUNDS):
* gutter.h (FRAME_TOP_GUTTER_BOUNDS):
* input-method-xlib.c:
* input-method-xlib.c (XIM_SetGeometry):
* redisplay-output.c (clear_left_border):
* redisplay-output.c (clear_right_border):
* redisplay-output.c (redisplay_output_pixmap):
* redisplay-output.c (redisplay_clear_region):
* redisplay-output.c (redisplay_clear_top_of_window):
* redisplay-output.c (redisplay_clear_to_window_end):
* redisplay-xlike-inc.c (XLIKE_clear_frame):
* redisplay.c:
* redisplay.c (UPDATE_CACHE_RETURN):
* redisplay.c (pixel_to_glyph_translation):
* toolbar.c (update_frame_toolbars_geometry):
* window.c (Fwindow_pixel_edges):
Get rid of some redundant macros. Consistently use the
FRAME_TOP_*_START, FRAME_RIGHT_*_END, etc. format. Rename
FRAME_*_BORDER_* to FRAME_*_INTERNAL_BORDER_*. Comment out
FRAME_BOTTOM_* for gutters and the paned area due to the
uncertainty over where the paned area actually begins. (Eventually
we should probably move the gutters outside the minibuffer so that
the paned area is contiguous.) Use FRAME_PANED_* more often in the
code to make things clearer.
Update the diagram to show that the bottom gutter is inside the
minibuffer (!) and that there are "junk boxes" when you have left
and/or right gutters (dead boxes that are mistakenly left uncleared,
unlike the corresponding scrollbar dead boxes). Update the text
appropriately to cover the bottom gutter position, etc.
Rewrite gutter-geometry code to use the FRAME_*_GUTTER_* in place of
equivalent expressions referencing other frame elements, to make the
code more portable in case we move around the gutter location.
Cleanup FRAME_*_GUTTER_BOUNDS() in gutter.h.
Add some #### GEOM! comments where I think code is incorrect --
typically, it wasn't fixed up properly when the gutter was added.
Some cosmetic changes.
