Previously, we were ignoring the scale of the editor in the second
paint step. If you were zoomed in, the size while you were drawing
was not the same as the size of the final shape.
The prior commits add the `DrawMode` enum to keep track of where
the shape is being drawn from. With this addition, the prior `Mode`
enum name is confusing, so this commit renames it to `FillMode` to
be more explicit :^)
Like other common image editing applications, now if you press
`alt` while drawing an ellipse, it uses the starting position as
the center of the ellipse as opposed to one of the corners of the
bounding rect.
The EllipseTool class now keeps track of a `DrawMode`, which is
either `DrawMode::FromCorner` (default), or `DrawMode::FromCenter`
(the option added by this commit).
The `draw_using()` function was modified to now take in the start
and end positions and construct the `ellipse_intersecting_rect`
itself, since we need to construct it differently based on the
drawing mode.
Some tools (e.g. ZoomTool) doesn't need layer to work. This commit
makes mouse events fire even if there is no layer. This fixes
a bug that ZoomTool didn't work when there is no layers.
This commit adds a Tool::MouseEvent struct, which contains events that
may be needed by tools: layer-relative, image-relative and raw (editor-
relative) event.
The raw event is used by ZoomTool to properly pan the view. This fixes
a bug which caused image to snap out of sight.
This adds support for the Tools in PixelPaint to use different cursors
within ImageEditor. For now most of them get the crosshair cursor since
it's the most fitting, but in the future we will want to add custom
cursors.
