For switch cases where existing comments or code flow logic obviously
intended to fall through, add a gcc-7 /*-fallthrough*/ comment to
silence warnings about this. Some cases which are less obvious are not
converted, so the code does not yet compile clean with
-Wimplicit-fallthrough.

Rename symbol OGL to DXX_USE_OGL to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.
This is a mostly automated transform, but the changes to SConstruct were
manual.
git grep -lzw OGL -- '*.h' '*.cpp' | xargs -0 sed -i -e 's/\(\s*#\s*if\)def\s*OGL/\1 DXX_USE_OGL/' -e 's/\(\s*#\s*if\)ndef OGL/\1 !DXX_USE_OGL/' -e 's/\(\s*#\s*if !\?\)defined(OGL)/\1DXX_USE_OGL/'
Rename symbol EDITOR to DXX_USE_EDITOR to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.
This is a mostly automated transform, but the changes to SConstruct were

GCC std::array uses std::size_t for its size_type. On Linux/amd64,
`std::size_t` is `unsigned long`. On Win32, `std::size_t` is
`unsigned int`. This provokes format string warnings because an
unsigned int is passed where the format string declares an unsigned
long. On Win32, `unsigned int` and `unsigned long` are the same size,
so `unsigned long` could have been used to avoid this problem by
maintaining consistency with Linux, but it was not. This may have been
an attempt to achieve bug compatibility with Microsoft's types.
Add a workaround by defining a macro DXX_PRI_size_type in the style of
inttypes.h PRI* macros. Use an SConf test to determine the correct
value by inspecting which compilation runs succeed. Currently, Linux
needs "l", Win32 needs "", and Win64 needs "I64".
This pass only targets commonly used standard types.

C casts do not require parentheses. C++ casts require grouping around
the target. Prepare for conversion to C++ casts by adding otherwise
unnecessary parentheses around the target of some C casts.
This pass attempts to process expressions that involve parenthesized or
bracketed subexpressions, but only if those subexpressions do not
themselves contain parenthesized or bracketed subexpressions.

Mac OS X defines uint_fast32_t to unsigned int, causing ambiguous
overloads between RAIIdmem::operator[](std::size_t) and
RAIIdmem::operator[](int). Adding a disambiguating overload for OS X
breaks Windows. Remove operator pointer and operator[]. Rely on the
inherited operator[] for indexing. Require users to call ->get() to
convert to a simple pointer.

Modifying a by-value temporary does not affect the underlying container,
so modifying it is almost always a bug. Require use of a by-reference
capture when modification is desired.
