Allow -1 for the hotspot coordinates in gdk_cursor_new_from_pixbuf,
if the pixbuf contains the x_hot/y_hot options with appropriate values.
Bug #632140.
In particular, the following functions are gone:
- gdk_screen_get_default_colormap()
- gdk_screen_set_default_colormap()
- gdk_screen_get_system_colormap()
- gdk_screen_get_rgba_colormap()
This way, we can specify a colormap when constructing windows. And ew
must do that to avoid BadMatch from XCreateWindow when we use a
different visual.
Also add a priv pointer to GdkVisual and use it for the GdkVisualPrivate
structure. Then Make GdkVisualPrivate actually private to
gdkvisual-x11.c and make other callers use proper function calls to
access it.
Direct and TrueColor visuals don't alloc colors, so they don't need to
fiddle with colormaps. Just copy the code that computes the pixel value
from gdkcolor-x11.c and use it. For other visual types, don't set the
background color and fallback to background = None.
No more GdkPixmap to store the icon and its mask, but instead use cairo
surfaces. Also render the icon into the surfaces using Cairo instead of
gdk_pixbuf_render_threshold_alpha().
Now the window background is a cairo_pattern_t. The backends will try to
set this as good as they can on the windowing system, but no guarantees
are made on wether the windowing system supports the pattern.
Also gets rid of GDK_NO_BG as undefined behavior is not a good idea to
support, and GDK_NO_BG effectively made the window's contents undefined.
It wasn't effectively used in GTK anyway.
Basically copies the code for setting the WM icon hint from GtkWindow to
GdkWindow. This achieves the following:
- Putting this X11 specific code into the X11 backend
- Enables removal of gdk_window_set_icon()
- Gets rid of Pixmap/Bitmap usage outside of GDK.
trap->end_sequence is the first serial for which we don't
ignore errors anymore, so we know the trap is dead if
end_sequence <= processed_serial.
Bug 629608
Currently fprintf(stderr, ...) is used for X error and X IO errors
(unless compiled with debugging, in which case g_error() is used for
X errors.)
But if an application is redirecting log messages, we really want
X errors to appear in that same log, so it's better to use a g_logv()
variant.
Though g_warning() isn't really appropriate for "lost connection to the
server", G_LOG_LEVEL_INFO isn't part of the "prefixed log levels"
so will produce output without the application name and PID.
