+
+# Poppler supports two different backends: Cairo and Splash (a low-level backend inherited from Xpdf).
+# Although Cairo renders better and faster than Splash, the Qt bindinds for Poppler currently only supports Splash due to political reasons:
+# https://bugs.freedesktop.org/show_bug.cgi?id=25240
+
+# This package is based off of Paul Gideon Dann's poppler-qt-lcd package, which uses Cairo as the default backend for the Qt4 bindings and also includes patches for subpixel rendering in Cairo.
+# (The subpixel rendering patches are not included in this package.)
+# https://aur.archlinux.org/packages/poppler-qt-lcd
+
+# The included patches add Cairo support to the Qt5 bindings and set Cairo as the default backend.
+# The patches are based off of Paul Gideon Dann's patches for the Qt4 bindings:
