[vfs] CFile: remove 'virtual' from destructor
no class is derived from CFile
[3d] added 3D subtitle depth
vdpau: move cropping of top and bottom lines to renderer
Revert "[nfs] - better fix for fe97d68f87d6985b2bf57d8e942b36b5e7373066 - possibly fixes #14727 - thx jm for the idea :)"

This reverts commit dd4dd2e91bc083a23fe7b46ae4c291c6672d32e0.

This commit created issues comparing paths when the export and the path was the same and did not contain a trailing slash, in addition, it removed the correct reversal of ordering of m_exportList generated by GetExportList.

    [nfs] replacement fix for dd4dd2e91bc083a23fe7b46ae4c291c6672d32e0 (issue #14727).

    If the exportPath is the same as the path is then bypass the substr methods, and return the correct relativePath.

Change the string comparison in CGUITextLayout::UpdateW to be case-sensitive

It seems likely that it was only case-insensitive due to the the default
seting of CStdStr::Equals. It's unlikely that you'd ever want to update a
string with another which is the same except for the case of one or more
characters, but if you did, I doubt you'd want to use the cached version if
so. And you're slowing down the comparison in all other cases to achieve that
dubious behaviour.
Add caching of text labels at the UTF8 level

Previously, CGUITextLayout::Update converted its string argument from UTF8 to
UTF16, then passed it to CGUITextLayout::UpdateW, where it was compared
against a cached copy of the string (in its UTF16 form). However, the
conversion itself was taking up a reasonable chunk of CPU time.

This patch adds a similar cache of the string in its UTF8 form to the Update
method, and splits the non-cache part of UpdateW into a separate function, so
we can bypass it the case where we've tested it against the UTF8 cache.

I have measured the effect while the Videos window of the default skin was
open (but idle) on a Raspberry Pi, and this reduced the CPU usage by 2.9%
from 39.1% to 36.2%:

          Before          After
          Mean   StdDev   Mean   StdDev  Confidence  Change
IdleCPU%  39.1   0.9      36.2   0.5     100.0%      +8.1%
