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 cells 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.
