Added new tool to lighten/darken. By default is in lightening mode. If the
user holds ctrl/cmd while using the tool, switches to darkening mode.
If the user holds shift while using the tool, then each pixel can only be
modified once per tool usage (ie user keeps hovering the same pixel, it
won't get lighter/darker after the first time). Can be useful if you want
to keep control of the amount of colors in the sprite.
TODO :
- Ability to select explicitly lighten/darken (context menu for
tools).
- Ability to set the 'step' (ie the strength of the lighten/darken)
- can use BACKSPACE key to delete selection content
when no selection, backspace retains the default behavior
- cursor for rectangle selection has been changed to crosshair
- fixed a bug where selection seemed to be cropped when released out of
the visible canvas
Issue was coming from the cached frame renderer.
During the window resize, we update the displaySize of the frame renderer,
regardless of the fact that the dimensions changed or not.
The setDisplaySize triggers a destruction of the canvas. But the
CachedFrameRenderer will render the frame only if it detects a change. In
this case, setDisplaySize has been overrided in CachedFrameRenderer to
skip any processing if the dimensions didn't change.
This behavior could be actually done in the FrameRenderer itself, but
since this is crucial to the CachedFrameRenderer behavior, I prefer to
keep it in this class.
Alternatively, could implement a way to discard caches of
CachedFrameRenderers from the outside.
