Reset the canvas size request from gimp_display_shell_constructed() in
gimp_display_shell_canvas_size_allocate() so the image window can be
made smaller again. GTK+ 3.x always respects size requests.
Remove all clipping hacks for drawing the canvas background, turns out
they never worked and we were relying on the pattern set on the
window, gah!
Also remove deprecated attempts to get a backgroud color and simply
don't show a color box in the menus for "from theme" cases.
we were not using a single GtkStatusBar features, it was only in the
way. Remove broken size allocation logic and simply set a minimum
height of 3em in CSS. Also ellipsize the label, long labels had funny
effects since changing the overall GimpDisplayShell packing to pure
GtkGrid.
- Fix gimp_scroll_adjustment_values() for smooth scroll events
- Set GDK_SMOOTH_SCROLL_MASK on all widgets where we set GDK_SCROLL_MASK
- Add GIMP_ZOOM_SMOOTH to enum GimpZoomType
- Add "gdouble delta" to gimp_zoom_model_step()
- Change the meaning of the "scale" parameter to "scale or delta" in
all functions that take GimpZoomType and a scale factor.
In gimp_display_shell_canvas_tool_events(), use
gdk_window_set_event_compression(), instead of implementing our own
motion compression, which used to introduce all sorts of weird
effects when combined with extended input devices, that we had to
hackishly work around.
For tools that use GIMP_MOTION_MODE_EXACT, we call
gdk_window_set_event_compression() to disable motion compression
for the canvas window upon initializing the tool in response to a
GDK_BUTTON_PRESS event, and again to re-eanble compression upon the
corresponding GDK_BUTTON_RELEASE event.
This commit also merges
gimp_display_shell_canvas_tool_events_internal() back into
gimp_display_shell_canvas_tool_events(). The split was a detail
of our custom motion compression implementation.
In gimp_display_shell_draw_image(), enable the code that adjusts
the scale-factor used for rendering the image by the window scale
factor, so that we make full use of the screen resolution even on
HiDPI displays. This also fixes artifacts along render-chunk
borders.
and use it where we used to pass gimp_button_menu_position() to
gimp_ui_manager_up_popup(), remove gimp_button_menu_position() because
it's now unused.
- add new "device from event" apparatus that works on GTK+ 3.x
- fix the active device selection mechanism
- use the new device grabbing functions
- make sure we don't process events while we have a grab on
another device
- compensate for some really obscure (and likely broken) behavior
of XI2, it feels like we are the first real users...
