libxrender1-dbg 1:0.9.6-2build1 (armhf binary) in ubuntu precise

 The X Rendering Extension (Render) introduces digital image composition as
 the foundation of a new rendering model within the X Window System.
 Rendering geometric figures is accomplished by client-side tessellation into
 either triangles or trapezoids. Text is drawn by loading glyphs into the
 server and rendering sets of them. The Xrender library exposes this
 extension to X clients.
 .
 This package provides an unstripped shared object with debugging symbols,
 useful to provide a backtrace with symbol names in a debugger; this
 facilitates interpretation of core dumps, and aids in finding logic errors in
 programs using this library (or the library itself). The library is
 installed in /usr/lib/debug and can be used by placing that directory in the
 LD_LIBRARY_PATH environment variable when the code to be debugged is
 executed. Non-programmers will likely have little use for this package.
