Currently a file with a .9.png extension will only have its @2x variant
found if it follows this format:
foo.9@2x.png
Since ".9" should be considered part of the file suffix, it should
ideally be able to look like this and still be picked up:
foo@2x.9.png
This patch makes qt_findAtNxFile() account for .9.* extensions.
This is needed for the image-based style support in Qt Quick Controls
2, which uses 9-patch images.
qmlbench benchmark results using
benchmarks\auto\creation\quick.image\delegates_image.qml with
QT_SCALE_FACTOR=2 show no difference in performance after this patch
is applied.
[ChangeLog][QtGui] High DPI variants of 9-patch images can now be
loaded using the following syntax: "foo@2x.9.png"

Qt already supports high DPI icons using the “@nx” approach, where the
device pixel ratio that the image was designed for is in the file
name. However, our implementation of the freedekstop.org Icon Theme
specification did not support the Scale directory key:
https://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html#directory_layout
This meant that users creating icons via QIcon::fromTheme() did not
get high DPI support. This patch fixes that.
[ChangeLog][QtGui][QIcon] Implemented support for Scale directory key
according to Icon Theme Spec. Icons created via QIcon::fromTheme()
now have high DPI support by specifying the Scale in the appropriate
entry of the relevant index.theme file.
