Don't call tool_control functions twice in init(). Call activate() and
halt() only on button_press() and button_release() to indicate that
the tool wants motion events.
not GimpCanvasLine* etc. We keep them around as items, and their
constructors return items, and it's getting more code anyway when
porting away from pause/resume, so let's keep the casting minimal at
least.
Instead, keep around the created GimpCanvasItems, and update them when
the blend coordiates change. Add setters to GipmCanvasLine and
GimpCanvasHandle which take care of calling begin_change() and
end_change() on the items around the change, so thes invalidate
properly.
Instead, add drawable, transform, x1, y1 etc. properties. This is
cleaner and has the nice side effect of not leaving artifacts, because
the changed state of the transform tool doesn't affect the extents
calculation any longer.
and use the stuff from GimpTransformOptions directly. The copied
values were only there because of XOR drawing. Also did some more
cleanup and junk removal.
And remove all the complicated handling code entirely. This makes
GimpTransformTool a lot less complex. As a nice side effect, the
preview is now always 100% in sync with the grid and handles.
instead of keeping them around as members. This is another artifact
from ancient times. Also get rid of some more legacy junk
code. Disable more code in GimpTransformToolUndo but keep it around
even though it does nothing at the moment.
It made the transform code hard to read and never belonged into the
tile manager anyway. It's a simple pixel buffer that should not know
about any position in an image. Instead, pass around the offsets of
tile managers explicitly, so everything is less obscure for the price
of having more parameters. This will also help replacing TileManagers
with GeglBuffers.
which was there for the purpose of transfomring the same buffer
multiple times (which would be nice but is broken and disabled for
ages). Also remove some junk that was there for unknown reasons, this
tool has a long history.
- add a double "progress" property to GimpOperationCageTransform
and update it every 20 rows
- connect to the notify::progress in the tool and display a tool
progress
- completely halt the tool before starting it
- bail out on options changes when the tool is not active
- initialy set the mode to CAGE_CHANGE
- indentation, formatting, various small cleanups
