v1.1.75

Automatic build of main — version 1.1.75.

Changes since v1.1.74 / Nouveautés depuis v1.1.74

fix(packaging): actually ship the WebP (and TIFF) codec (issue #19)

WebP and TIFF were already offered in Open/Save, but Qt decodes them through
runtime image-format PLUGINS that aren't linked — so they silently failed unless
qt6-image-formats-plugins happened to be installed:

• .deb: added it to CPACK_DEBIAN_PACKAGE_DEPENDS (SHLIBDEPS can't see plugins).
• AppImage: installed on the CI runner so linuxdeploy bundles libqwebp/libqtiff.
• CI / package build: same package added.
• Flatpak: the org.kde.Platform runtime already includes qtimageformats, so no
  change needed there.

Adds a WebP round-trip test that runs where the codec is present (CI) and skips
cleanly on a bare dev box. No UI change — WebP is just a working entry in the
file dialogs now. Free-angle rotation was already present (Layers ▸ Rotate/Zoom).

Tests: 431 (+ the guarded webp round-trip).

sudo apt update && sudo apt install paint.software

Or download the .deb below and sudo apt install ./paint.software_*_amd64.deb.

Any distribution — Fedora, Arch, openSUSE…

AppImage (portable, no install — download, then):

chmod +x paint.software-*-x86_64.AppImage && ./paint.software-*-x86_64.AppImage

Flatpak (download paint.software.flatpak, then):

flatpak install --user paint.software.flatpak
flatpak run io.github.univers4craft.PaintSoftware
