New actions in the Layer Menu allows for the creation of a new layer
from the current selection. Layers can be made by copying the
selection or cutting it from the current layer. The new layer will be
sized to the bounding box of the selection. The newly produced layer
will be added to the layer stack.
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

Vectorscopes are a standard tool in professional video/film color
grading. *Very* simply, the Vectorscope shows image colors with hue as
the angle and saturation as the radius; brightness for each point in the
scope is determined by the number of "color vectors" at that point. More
specifically, the Vectorscope shows a 2D UV histogram of the image,
where U and V are the chroma ("color") channels of the image.

This adds menu item icons for Add Mask, Flatten Image, Fit Image To
View, and Generic 5x5 Convolution.
This modifies the menu item icon for Swap Colors to make the action more
obvious and improve accessibility.
This command finds the smallest non-empty content bounding rect
by looking for the outermost non-transparent pixels in the image,
and then crops the image to that rect.
It's implemented in a pretty naive way, but it's a start. :^)
Instead of having "Flip Horizontally" in both the Image and Layer menus,
we now have "Flip Image Horizontally" and "Flip Layer Horizontally".
This same concept applied to other, similar actions.
The Undo/Redo actions now tell you what kind of action will be
undone/redone. This is achieved by adding an "action text" field to the
ImageUndoCommand and having everyone who calls did_complete_action()
provide this text.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
This adds a simple histogram widget that visualizes the rgb-channels
and brightness for a given image. When hovering over the image it will
indicate what brightness level the pixel at the mouse position has.
This is in preparation to support masking of Layers. We now distinguish
between the "display_bitmap" which will be the whole Layer with every
effect applied and the "content_bitmap" which contains the actual
unmodified pixels in the Layer.
This makes it consistent with `ImageViewer`, where `F` was unavailable
for use as a shortcut. A small change, but it's nice having the same
keyboard shortcuts where we can :^)
We often want to zoom and fit the content of the widget into the
visible frame (or some rect within the frame), and it makes sense to
move this functionality into the AbstractZoomPanWidget to minimize
the amount of coordinate math derived classes need to do.
This commit moves the code that implements this functionality from
`PixelPaint::ImageEditor` into `AbstractZoomPanWidget` so that we
can also use it for other applications (such as ImageViewer!)
The ImageEditor tracks whether it was loaded from an image
(the alternative being a project file.) If it was loaded from an image
file we redirect save project actions to save as instead.
After closing the last open ImageEditor, selecting a color would try to
dereference it causing a crash. Instead make set_image_editor() take a
pointer to it and set it to nullptr when closing the last tab like we
do with LayerListWidget and LayerPropertiesWidget.
Previously, we would clear it if there was still an editor open. This
was not obvious because it was only visible when an inactive tab was
closed, since closing an active tab would trigger an editor change
which would re-fill the layers widget.
This allows us to request any specific editor to close itself. Earlier,
this could only be done for the currently active editor, so trying to
close inactive tabs would not work properly.
Previously the save logic was hardcoded to only work for the active
editor, so closing editors in the background would not properly
handle the unsaved changes. This patch brings us closer to be able
to fix that problem.
The rotate clockwise/rotate counterclockwise actions can be added to
CommonActions since they are repeated in FontEditor, ImageViewer and
PixelPaint. This keeps the shortcuts and icons consistent across
applications.
This is just a slight variation of `/res/icons/16x16/paste.png`, I've
removed the lines on the paper to make it look consistent with the
"New Image" icon, which is an empty piece of paper.
I think this is likely the more common operation and makes more sense
in the toolbar. It calls the 'save as' action internally anyway if there
is no associated file.
Now, when trying to close the application, there is a separate prompt
for each open tab with unsaved changes. Each tab is closed after it is
handled appropriately (assuming the user didn't Cancel), this makes it
so that the message box is always asking about the currently active tab,
allowing the user to see that the image contains.
If at any point the user presses "Cancel", all remaining tabs are kept
open.
