The eglgears application depends on 'sqrt'. With the old tool chain,
this symbol was resolved through the dependencies of the 'gallium'
library. This does not work anymore for the new tool chain.
A similar issue arised for avplay, where we need to explicitly
state the av components in the LIBS declaration of the target.
With this patch the SDL-based 'avplay' media player, which is part of
'libav', can be built. The run script expects a media file named
'mediafile' in the 'bin' directory.
Fixes#216.
This patch introduces the basic key handling required to browse through
a multi-page PDF document ([page-up] or [enter] -> next page,
[page-down] or [backspace] -> previous page).
This way, we can register a meaningful 'user_data' pointer to at the
'pdfapp_t' structure and avoid the use of singletons for 'Framebuffer'
and 'pdfapp'.
This version of MuPDF will use Genode's framebuffer session and input
session to display a PDF file. At the current stage, the program is
merely a skeleton that compiles and starts. Neither the actual rendering
not the response to user input are implemented. To try it out, there
is a ready-to-use run script at 'libports/run/mupdf.run'.
