[vlc-devel] [PATCH 00/24] Refactor OpenGL renderers

[Romain Vimont]

The rendering of both video pictures and SPU was handled in vout_helper (using
some data from opengl_tex_converter_t).

In order to separate concerns, implement a main renderer and a SPU renderer as
separate "components".

As a result of this patchset:

 - there is no opengl_tex_converter_t anymore;
 - there is a vlc_gl_renderer (renderer.c) which draws the main pictures;
 - there is a vlc_gl_sub_renderer (sub_renderer.c) which draws the SPU;
 - the vout_helper just delegates _Prepare() and _Display() to the renderers.

For your convenience, here is a branch:
