locking focus on an image with no representations.

size (0, 0)
* Source/NSCachedImageRep.m: Throw an exception if you attempt to create a cached
image rep with a size of (0, 0).
git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/gui/trunk@33819 72102866-910b-0410-8b05-ffd578937521
because we now cache the entire representation and not the rep scaled
to the image's size.

on backends supporting GSdraw: (cairo). This means we don't have to
create a window for every call to draw an image, and gives me a 5-10x
speedup for image drawing.
* Source/NSCachedImageRep.m: Implement private method
-nativeDrawInRect:.. which is called by NSImageRep's
-drawInRect:fromRect:..., and efficiently draw the cached rep
using GSdraw:. Also make some changes so cached image reps can have a
DPI != 72.
* Headers/AppKit/NSCachedImageRep.h: New private init method that lets
you specify diferent pixel size and point size.

-drawInRect:fromRect:operation:fraction:respectFlipped:hints: method
* Source/NSImage.m:
* Source/NSImageRep.m: Refactor drawing code from NSImage to NSImageRep.
This should cause no functionlity change, but it lets NSImageRep
subclasses implement more efficient versions of -drawInRect:fromRect:...
that don't involve the (expensive) drawing of the image in a temporary
offscreen window and then drawing from there on to the destination surface.

* Source/NSCustomImageRep.m:
- Don't retain the delegate (matching OS X)
- Remove unnecessary flip checks from -drawAtPoint: and -drawInRect:
to match the code in NSImageRep
- Fix a mistake when setting the ctm scale factor

demonstrated in GSTest:
- drawing an image in a flipped view with -drawInRect:... wasn't
working, and
- drawing a vector rep in a dest rect larger than the point
size of the rep was resulting in blurry output.

which chooses the smallest rep larger than or equal to the provided size.
Modify -nativeDrawInRect:... to use the above method for choosing a rep.

earlier in -nativeDrawInRect:... and replace them with saving/restoring
the transformation matrix. The DPSgsave/DPSgrestore were causing problems
when drawing images with a non-rectangular clipping area.

It should now be very close to the algorithm described in the cocoa
drawing guide, and fixes numerous bugs with the old code.

left by my last commit to this method.

NSDeviceResolution
* Source/NSImage.m: Implement -_bestRep:withResolutionMatch:
* Images/common_Dimple.tiff:
* Images/common_3DArrowRight.tiff: Add to these images
a second 'page' at 4x the original resolution which I drew.
If you use GSScaleFactor > 1 then the high resolution version
of these images should be used.

large enough so that detail is preserved when drawing using a scale factor
larger than 1. This change should only improve output quality but not
affect image drawing otherwise.

New simple implementation which calls
-drawAtPoint:fromRect:operation:fraction:.
Also respects the user space scale factor.
* Source/NSImage.m (-guiDrawInRect:fromRect:operation:fraction):
Remove a special case which called -compositeToPoint:..., which would
cause an infinite loop when combined with the above change.
Also avoid using -drawRepresentation:inRect: because -drawInRect:...
is supposed to fill the destination rect regardless of the setting
of -scalesWhenResized. This is a change borrowed from
-nativeDrawInRect:...

from NSImage category.
* Source/NSImage.m: Added code in _setImage:forName: to archive
by name instead.

* Source/GSTheme.m: Call method _setArchiveByName: with YES so that
images loaded by a theme will not be persisted as image data, but
rather as references. This will avoid an issue with saving theme
images when saving files in Gorm while a theme is loaded.
* Source/NSImage.m: Added method _setArchiveByName:.

See bug report #27782
In particular, fixed -[NSImage drawXXX] and -[NSImage composite/dissolveXXX]
methods to work exactly as Cocoa when the Cairo backend is used.
Added a new draw operator (in addition to composite) to the backend. Cairo is
the only backend that implements it for now.
Eliminated as many flipping checks as possible.
Warning: Untested with the winlib backend.
You must update, recompile and install both Back and Gui.
