scene palette shader crashfix

Seems to still build in lol, will check other works to be sure

This will help us deal with shader name collision. Breaks the Windows
build for the moment, unfortunately.

This allows actors to perform draw commands in TickDraw(), even
if it’s not exactly what we want in the future.

All these changes will allow us to more easily add Lol Engine as a
submodule of another Git project.

- removed 0 CR characters
 - removed 1 trailing whitespaces
 - replaced 1 tabs with spaces
 - fixed 367 svn:eol-style properties

Not all programs support this feature for now, but that’s because they
don’t support the scene framework either, and will need patching. Also
the default postprocess is deliberately exaggerated for now.

We already have the convenient degrees() and radians() functions to convert
between angle formats. This commit involves a lot of refactoring here and
there and I may have missed some places where conversions were needed. But
hopefully there aren’t may such places.

The old public API is maintained for now but should be considered
deprecated.

The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.
