+     "Dear ImGui is a @acronym{GUI, graphical user interface} library for C++.
+It creates optimized vertex buffers that you can render anytime in your
+3D-pipeline-enabled application.  It's portable, renderer-agnostic, and
+self-contained, without external dependencies.
+
+Dear ImGui is aimed at content creation, visualization, and debugging tools as
+opposed to average end-user interfaces.  Hence it favors simplicity and
+productivity but lacks certain features often found in higher-level libraries.
+It is particularly suited to integration in game engine tooling, real-time 3D
+applications, full-screen applications, and embedded platforms without standard
+operating system features.")

+powerpc: fix build failure on power7 and older (#532)
+
+Build failure looks as:
+```
+libtool: compile:  powerpc-unknown-linux-gnu-gcc \
+    -O2 -mcpu=powerpc -mtune=powerpc -pipe ... -c src/powerpc/ffi.c ...
+In file included from src/powerpc/ffi.c:33:
+src/powerpc/ffi_powerpc.h:65:9: error: '__int128' is not supported on this target
+   65 | typedef __int128 float128;
+      |         ^~~~~~~~
+```
+
+The fix avoids using __int128 in favour of aligned char[16].
+
+Closes: https://github.com/libffi/libffi/issues/531
