Owen Taylor 4851efe296 configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on
Sun May  3 13:38:22 1998  Owen Taylor  <otaylor@gtk.org>

	* configure.in acheader.h gdk/gdkwindow.c
	Check for Shape extension both on the client and server
	side. (And, more importantly, check for the shape extension
	so we may include -lXext even when compiling with --disable-xshm)

	Don't set override_redirect on all shaped windows. It isn't
	necessary.

	* gdk/gdkwindow.c: Set ->colormap to NULL for root
	and foreign windows. Use this to check if we
	need to get the colormap from X.

Fri May  1 22:32:47 1998  Owen Taylor  <otaylor@gtk.org>

	* gtk/gtkbutton.c (gtk_button_paint): Draw the areas
	between the default and the button always in GTK_STATE_NORMAL.

	* gtk/gtkrange.c (gtk_range_style_set): Added a style_set
	callback.

Fri May  1 16:40:57 1998  Owen Taylor  <otaylor@gtk.org>

	* gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]):
	  Fix a buffer overflow on pixmaps that claim to have
	  more than 31 characters per pixel.

	  (gdk_pixmap_read_string): Don't wrap around strings longer
 	  than half of address space ;-)

	* gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers
	that were used for printing integers.

	* */* (almost):

	Style: All
	  int foo () { ... }
	changed to
	  int foo (void) { ... }

^^^^^^^ This is why some many files changed

	Even where there were proper prototypes elsewhere.

	* gdk/gxid.c (handle_claim_device): Some extra checks.
	It isn't safe against being fed bad X id's, but at
	least it should be safe against deleting all your
	files.
