Rather than applying the translation offsets to the vertices, now applies them to the model view matrix from the top of the matrix stack and pushes it over to OpenGL. The vertices themselves are still all held client-side.
Enable hardware clipping.
Move the vertex data across to a vertex buffer object just prior to drawing.
Move vertex data into an OpenGL VBO when the font cache entry is populated.

The font cache now stores the "name" (handle) of the VBO, rather than a vector
of vertices.
Switch from glDrawArrays() to glDrawElements().

This involves setting up a static VBO containing the indexes necessary to
convert from quads to triangles on the fly in the GPU.
Improved file buffering in CArchive

Even though memcpy is typically inlined by the compiler into byte/word loads
and stores (at least for release builds), the frequency with which 1, 2 and 4
byte loads/stores are encountered in cases where the size is *not*
determinable at compile time is still high enough that it's worth handling
these specially. On the ARM1176JZF-S in the Raspberry Pi, this improves the
total time to open a library (in the case where it's fetched from a CArchive)
by around 4%.

It should be noted that this code uses 16-bit and 32-bit word loads and
stores that are not necessarily aligned to their respective widths. It is
possible that there are some architectures out there which do not support
this, although all ARMs since ARMv6 have supported it (and ARMs earlier than
that are probably not powerful enough to be good targets for XBMC).
[mmal] Allow mmal codec for dvd stills
[omxcodec] Don't force software codec with dvds
[omxplayer] Don't propagate 3d flags based on supported 3d modes
[graphics] Don't set stereo mode based on resolution

The resolution change should follow stereo mode
[graphics] Allow switching to a more suitable 3D resolution
[3D] Support switching to 3D resolutions

Include matching 3D flags (SBS/TAB) in the score of a resolution to switch to, to enable switching to 3d modes.
Also remove the old code that treated 3D modes differently when assigning a score.
[graphics] Make pixel ratio for 3d modes consistent

Note: Use the stored stereo flags from lists of resolutions.
Use current stereo mode for current resolution.
filesystem: Make support of browsing into archives optional

The ability to browse, scan and play content in archives can cause problems on low powered/low memory devices.
It's quite common to see reports of a large rar file that causes xbmc to crash with an out-of-memory error when browsing or scanning.
It also can be slow as any archive in the directory is opened and extracted.

Add a settings option to enable this feature and default to disabled on Pi
