Using tabs aligns text correctly only if the viewer display tabs the
same size as the editor. Using spaces allows always having well aligned
texts, especially in table-like outputs like this dependency listing.
It seems we forgot to move librsvg from optional to mandatory
dependency. Also add RawTherapee as an optional runtime dependency.
Finally reorder the lists alphabetically.
Poppler and poppler-data are now hard dependencies.
PDF is a common-enough format nowadays that import support is likely
considered as a granted feature by everyone. Moreover the current
fallback to the PostScript plug-in for PDF support just gives a degraded
experience with less features (and probably a lot of bugs since
basically nobody uses this code).
Poppler-data is also considered mandatory because non-western language
support should never be considered an "option". People using non-western
languages are not second class citizens and therefore if we say that PDF
import is now a hard feature, it should also include PDF using CJK or
Cyrillic languages.
As of version 0.4.7, poppler-data has a pkg-config file, allowing us to
verify its presence. The configure summary is only informational, and we
don't impose this version since older versions may still work.
Moreover poppler-data is only a runtime dependency, so you can also add
it afterwards.
Fontconfig had a few bugs in the default configuration when compiled for
Windows. These issues are fixed from version 2.11.1. Display a warning
when compiling on win32 platform with older versions.
See in particular bugs 708110 and 703331.
