* Added the pivot system
* Some re-arrangement
* a bug-fix
* fixed a conversion scale bug
The problem was the conversion from rect to pixel scale was not properly done, i changed it so that it sets conversion factor of shorter side according to the longer side
* Fix to allow manual pivoting
* remove an update()
i may have added it my self but i think its not needed now
* made shader pivot consistent with gd script
by doing `pivot + Vector2(0.5, 0.5)` for "Nearest neighbour (Shader)"
* Cosmetics
* Formatting
* more formatting
* an optimization
* add limit change with brush
* Delete Draw.gd
* Delete BaseTool.gd
* added error calculation
* revert last commit
* Implemented OS.clipboard (using var2str())
* some sanity checks
* formatting
* use text system instead of os clibboard
* Add preferences for tile mode basis vectors
Each tile is offset according to the x and y basis. For example, a tile (1,1) would be at basis_x + basis_y
* Update tools for custom tile modes
Show the indicator in the correct position, and only draw on the nearest tile.
* Fix style issues
* Move tile functionality to own class to prevent bloating Project
* Fix error in Tiles bounding box logic
* Make tile mode offsets project settings
Since the desired tile mode offsets depends on the tile being drawn, the tile mode offsets should be a project specific setting which is persisted in the project file.
* Update TileMode object immediately after closing dialog
* Don't draw center tile by default in TileMode
* Move tile mode offsets to view menu
* Move tile mode offsets dialog out of ImageEffects
* Refactored `draw_tool`
In draw.gd, efactored the `draw_tool(position)` function to memorize a
few preliminary steps that may be skipped on every pixel.
* Reformat
* Reformat
* Improved _set_pixel
Memorized a few results per-stroke rather than recomputing them on each
pixel.
* Refactor
* Improved draw_tool_circle
Memorized the shape of the circle as a vector of displacements from
the center to avoid recomputing the whole circle at every position.
* Refactor
* Reworked drat tool methods
I changed the implementations to use private functions that return the
array of points that would be affected by the tool. This way, when we
are drawing a stroke of a tool, we can get all points affected by the
stroke, filter out duplicates, and only set pixels once.
* refactor
These changes allow users to set the left (or right) mouse buttons as mapped shortcuts to the transform snap grid action, in order to automatically snap to grid while moving a selection.
