Telling Windows that we support Windows 7 means it will stop catching
unhandled exceptions that occur in a callback from kernel mode, and
allow our own crash handler to catch then.
Direct3D hasn't worked for more than a year now, and there don't seem to
be any efforts to revive it. Remove it and concentrate on better OpenGL
support.
When reloading a function, C4AulParse didn't reset the parameter count.
This resulted in the function's ParCount to eventually increase above
C4AUL_MAX_Par, at which point parameter type checking would access
invalid memory.
When C4AbstractApp is destroyed, it will try to reset the current
video mode. This includes switching off the fullscreen flag of the
render window. When no render window has been created yet, for
example during the application initialization phase, this led to a
null pointer dereference due to a missing check.
libc4script requires the system string table, but doesn't require the
full-fledged C4Language. Move the table to C4LangStringTable to reduce
dependencies.
To make C4ComponentHost more reusable, move C4Language dependencies out
of the class.
LoadEx isn't really suited to reside in C4Language, but it's better to
have it there, since all C4Language consumers also use C4ComponentHost;
the reverse isn't true.
A large number of g++ versions ship a <regex> that declares all of the
required functions, but don't actually implement them, making using them
result in a linker error.
Fallback to Boost.Regex if the host C++11 <regex> implementation is
broken; the interface is the same anyway, only differing in the
containing namespace.
Unfortunately, Boost.Regex is not a header-only library, but this is not
a big deal because all major Linux distributions ship it, and Visual
Studio implements <regex> since 2010 (the oldest version we still
support).
ResTable (the main system string table) was a home-grown hashmap that
did not cope with collisions at all. Since we already have a proper
dictionary in C4LangStringTable, use that instead.
There's no point in calculating render positions or audio source
locations when we're not rendering any audio or graphics. Skip it when
headless to save CPU cycles.
This might make life easier for people who transition from Landscape.txt.
For new maps, lines should probably better be drawn using MAPALGO_Poly in a loop. This gives you more control over individual line widths, angles, etc.
