Fixes a regression found after merging #5414:
https://github.com/aseprite/aseprite/pull/5414#issuecomment-3286339563
We always expected a sRGB color in ui::Graphics API and we can specify
a color in another color space using the ui::Paint version of its
member functions.
Several functions related to color spaces are now using a ui::Display
to receive the specific display where we're going to paint, instead of
using os::System::instance()->defaultWindow()->colorSpace().
This fix solves color space missmatch in the following UI elements:
- Timeline thumbnails
- Palette entries
- Tileset entries
- Color Spectrum and Wheels
- Color Popup Gradients
- Color Button
This was originated for #1279 (CLI-only Aseprite) which can be
achieved with LAF_BACKEND=none anyway.
In this way we simplify the development process, and checking for the
availability of the GUI can be done in run-time through App::isGui()
or Context::isUIAvailable().
Right now it just creates a plain widget, but now we can specify
hexpand/vexpand arguments too so we can create a canvas with a fixed
size or with dynamic size (e.g. to use the whole dialog client area).
The onpaint event is not functional yet.
