Adds the bind `add_selection_for_next_occurrence` to TextEdit, with CTRL+D as the default shortcut.
When the bind is performed, ff a selection is currently active with the last caret in text fields, searches for the next occurrence of the selection, adds a caret and selects the next occurrence.
If no selection is currently active with the last caret in text fields, selects the word currently under the caret.
The action can be performed sequentially for all occurrences of the selection of the last caret and for all existing carets. The viewport is adjusted to the latest newly added caret.
The bind and the behaviour is similar to VS Code's "Add Selection to Next Find Match" and JetBrains' "Add Selection for Next Occurrence". It takes advantage of the multi-caret API.
The default shortcut for `select_word_under_caret` has been changed to ALT+G, in order to give priority to CTRL+D for `add_selection_for_next_occurrence` to better align with popular IDEs and editors.
1. Viewport::get_visible_rect().position is always zero.
So Control::get_window_rect is identical to Control::get_global_rect.
Remove Control::get_window_rect since it is not used in the source code.
2. sqrt(a * a) = abs(a) for doubles
3. Simplify affine_inverse combination
4. Simplify calculation in shaders
Removes separate `Command` key (use `Meta` instead).
Adds an event flag to automatically remap `Command` <-> `Control` (cannot be set alongside `Control` or `Meta`).
Update TextEdit gutters subcase, gutter add and remove to ensure gutter total width is correct
Fix test_code_edit symbol lookup test case to include padding (+2)
Affects a lot of classes. Very thoroughly checked signal connections and deferred calls to this method, add_do_method/add_undo_method calls, and so on.
Also renames the internal `_update_callback()` to `_redraw_callback()` for consistency.
Just a few comments have also been changed to say "redraw".
In CPUParticles2D, there was a private variable with the same name. It has been renamed to `do_redraw`.
Fixed line_drawing_cache not containing anything
Fixed is_move_caret_on_right_click_enabled requiring the context menu to be enabled
Fixed when selecting_enabled is false not disabling shift + click
Fixed when selecting_enabled is false not being able to drag the caret
Fixed _delete emitting signals when nothing had changed.
Fixed insert_line_at up causing a visual update
Fixed get_pos_at_line_column returning a valid position when it was invalid
Fixed set_caret_column unnecessary emitting "caret_changed" when the column is greater then the line
Fixed select_word_under_caret not accepting the edges of words
Fixed select_word_under_caret moving the caret to the start of the line when no word was found
Fixed get_selection_line and get_selection_column not checking if the selection was enabled
Fixed set_line_as_center_visible throwing errors if it would show line 0
Fixed set_line_as_center_visible being off by one
Fixed set_line_as_last_visible not being able to show the first line
Fixed pressing UP and the end of a wrapped line sending the caret to col 0 rather then then persevering the position.
Add "generate_mipmap" font import option.
Add some missing features to the Sprite3D.
Move BiDi override code from Control to TextServer.
Add functions to access TextServer font cache textures.
Add MSDF related flags and shader to the standard material.
Change standard material cache to use HashMap instead of Vector.
This can be used to make editor code more compact.
However, as of writing, these constructor arguments cannot be used
from the scripting API.
This was already provided for Label and CheckBox, but it was missing
for other Control nodes where it made sense to provide a default value.
