	* Source/NSWindow.m: ([-becomeKeyWindow]) Don't ask the backend to
	make us key unless we are visible.
	([-orderWindow:relativeTo:]) ask backned to make us key when we order
	in (if we should be key that is).

Tue Dec 14 11:15:00 1999  Richard Frith-Macdonald <richard@brainstorm.co.uk>

	* Headers/AppKit/NSMenuitemCell.h: Removed implementation cache ivars
	and added an ivar for temporary storage of background color.
	* Source/NSMenuItemCell.m: Removed draw implementation caching to
	decrease memory footprint, but added color and image class caching
	which will more than compensate in performance.  Also added use of
	highlight version of menu arrow.
	* Source/NSImage.m: minor image caching fixes and more debug statements.

1999-12-13    <fedor@gnu.org>

	* Source/NSWindow.m (-_processResizeEvent): Add DPScurrentgstate
	so DPS server knows we updated the backing buffer.

Mon Dec 13 20:00:29 1999  Nicola Pero  <n.pero@mi.flashnet.it>

	* Headers/AppKit/NSBrowserCell.h: Removed two ivars.  
	* Source/NSBrowserCell.m: Made allocation/deallocation faster; 
	added untested alternateImage support.

Mon Dec 13 16:06:36 1999  Nicola Pero  <n.pero@mi.flashnet.it>

	* Headers/AppKit/NSActionCell.h: Added ivar _control_view.
	* Headers/AppKit/NSBrowserCell.h: Use two bits to store two BOOL.
	* Headers/AppKit/NSButtonCell.h: Use a bit to store a BOOL.
	* Headers/AppKit/NSCell.h: Moved ivar _control_view to
 	NSActionCell.  Packed more ivars into the bitfield.  
	Added two bits in the bitfield for subclass use.  Removed 
	unused ivar _cell_size.
	* Headers/AppKit/NSFormCell.h: Use a bit to store a BOOL.
	* Headers/AppKit/NSTextFieldCell.h: Use two bits for two BOOL.
	* Source/NSActionCell.m ([-drawWithFrame:inView:]): Added 
	method, per spec.  
	* core/gui/Source/NSButtonCell.m: Updated.
	* Source/NSBrowser.m: Tiny optms in GSBrowserTitleCell.
	* Source/NSBrowserCell.m: Updated.
	* Source/NSButtonCell.m: Updated.
	* Source/NSCell.m ([NSCell -setControlView:]): Removed, this
 	method should not exist.  Moved actual implementation of
 	([-controlView]) to NSActionCell, as per spec.  Moved any
 	reference to _control_view to NSActionCell; in ([-performClick:]),
 	invoke [self controlView].
	* Source/NSControl.m ([-setCell:]): Updated.
	* Source/NSFormCell.m: Updated.
	* Source/NSImageCell.m: idem.
	* Source/NSMenuItemCell.m: idem.
	* Source/NSPopUpButtonCell.m: idem.
	* Source/NSTableHeaderCell.m: idem.
	* Source/NSTextFieldCell.m: idem.

	* Headers/AppKit/NSColorWell.h: Removed unused ivar. 
	* Headers/AppKit/NSScroller.h: Removed unused ivar.
	* Headers/AppKit/NSView.h: Removed unused ivar needs_display.

	Cell optimizations: use a bitfield in NSCell to reduce memory
 	consumption; access cell ivars directly while drawing; minor speed
 	tricks here and there for cells; browser cells do not create any
 	longer an auxiliary cell each, thus hugely reducing time and
 	memory required to create browser cells.  To my great delight some
 	things are much faster now.
	* Headers/AppKit/NSActionCell.h: Prefixed all ivars with
 	underscores.
	* Headers/AppKit/NSBrowserCell.h: Removed unused ivar.
	* Headers/AppKit/NSButtonCell.h: Prefixed all ivars with
 	underscores; removed unused ivar.
	* Headers/AppKit/NSCell.h: Introduced a bitfield; prefixed all
 	ivars with underscores.
	* Headers/AppKit/NSSliderCell.h: Removed unused ivar.  
	* Source/NSActionCell.m: Optimizations.
	* NSBrowserCell.m: Important optimizations, rewritten.
  	([-setTextFieldCell:]), ([-setBranchImageCell:]),
 	([-setHighlightBranchImageCell:]): Removed unused private methods.
	* Source/NSButtonCell.m: Updated.
	* Source/NSCell.m: Important optimizations.
	* Source/NSComboBoxCell.m: Updated.
	* Source/NSFormCell.m: Optimizations.
	* Source/NSImageCell.m: Optimizations.
	* Source/NSMenuItemCell.m: Updated.
	* Source/NSPopUpButtonCell.m: Updated; ([-dismissPopUp]): Use
 	GNUstep close menu method.
	* Source/NSSliderCell.m: Tiny optimization.
	* Source/NSTableHeaderCell.m: Updated.
	* Source/NSTextFieldCell.m: Updated.
	* Source/NSBox.m: Updated for new way of getting border sizes.
	* Source/NSBrowser.m: idem.
	* Source/NSSlider.m: Minor optimization.
