Add undo to the Isissors tool, along with some refactoring:
- Always modify the actual curve, instead of a set of obscure states
kept around in the tool instance
- On cancel, simply go back to the curve on the undo stack
- Draw handles on top of curve segments
- Draw the currently edited segments and handles in the highlight color
Iterators might only give us a small chunk of the source buffer,
but until now convolve assumed it gave us the entire buffer at once.
This simply switches to gegl_buffer_get so we always have the
entire buffer.
This fixes iscissors.
The interaction is fully restored, it's also ported to the new halt()
and commit() API of tools and semi-properly GEGLized: the gradient map
is now constructed on the fly using a GimpTileHandlerValidate
subclass.
The only problem is that it doesn't find any edges in the image and is
totally useless. Pushing anyway to put an end to the bitrot, any help
with debugging is greatly appreciated...
Add virtual function validate() so subclasses can construct arbitrary
buffers on-the-fly. The default implementation blits from the
projection graph like before. Add boolean property "whole-tile" which
allows for switching between always validating entire tiles, and
validating the parts of the tile that are actually dirty.
Add new tool GimpHandleTransformTool which allows to freely place up
to 4 handles on the image, then move any one of them, which transforms
the image so that the remaining handles keep their position.
Did quite some cleanup on the code before pushing --Mitch
by getting rid of the complicated "previous selected points" handling
and simply keeping around the last motion event's coords for
calculating the deltas to move the selected points.
- Formatting and indentation
- Handle GIMP_TOOL_ACTION_COMMIT
- Fix calls to gimp_tool_control_activate()/halt()
- Move variables to local scopes
- Remove and reorder includes
- Remove redundant members from the tool struct
- Set members to NULL after freeing them
- And whatnot...
