This reverts commit 2226fb1dc8.
It doesn't make much difference right now, will work the same on
native builds and be broken on cross-builds.
I need to fix how invert-svg is built (broken on commit 84439a8),
so that it is a build executable again. Work in progress.
But since it makes no difference right now, let's just revert this
one already.
Observed initialization time for OpenCL observed on modern systems has been up
to 1 second - OpenCL speed ups will not outweigh initialization costs for these
small icons.
It was infinitely-looping because of a mis-usage of the % matching rule.
On the rule or dependency side, I must use $(@D) instead of % to match
the directory part of the target (I could also have used $* to get only
the matching part of the stem).
This will extract vectorial symbolic icons out of the SVG source, and
generate vectorial symbolic inverted icons too.
Vectorial color icons are not extracted yet.
I also make sure that the tools/ subdir is processed by make before
icons/ because a few build tools will be needed to extract the icons.
Yet I mark the feature as experimental because librsvg seems to be
broken on many edge cases and several icons end up wrong. I'll keep
the option experimental until I figure the right way to extract the
icons.
Fixed "gimpicons.c:30:45: fatal error: icons/Default/gimp-icon-pixbufs.c:
No such file or directory" after commits :
ee512b610dfa9e5b8f98
Fixed "ln: failed to create symbolic link ‘12/gimp-default-colors.png’:
File exists" by forcing new symlinking on creating get-default-colors.png
for Symbolic-inverted to prevent error during make.
They need to be properly dependent on the image with the same name
in the Symbolic icon theme. Until now we could only make them dependent
on either nothing or all Symbolic icons.
