Additions:

• Added more typed externs for built-in functions (matrices, clipboard, gml.sys.*, room manipulation, cameras...)
• Added @:noRefWrite for mapping global arrays that should be written to without [@] (such as built-in ones).
• Added @:dsMap for mapping typedefs to ds_maps (sample).

Improvements:

• You no longer need to manually set sfgml_next when targeting GMS2 - if the output file is a .yy, the compiler directive is added automatically.
• The library now automatically sets a few compiler directives based on target version features,
• sfgml_array_create: whether array_create is supported (GMS2 and >1.4.1763)
• sfgml_array_decl: whether [...] array initializer is supported (GMS2 and extensions in >1.4.1763)
• sfgml_ternary: whether ternary operator is supported (GMS2 and extensions in >1.4.1763)
• sfgml_copyset: whether copy-on-write array behaviour is safe to use (currently isn't)
• sfgml_version: target version, as set by you or automatically set based on file extension (current 1.4/2.x)
• sfgml_extension: whether compiling to an extension (rather than a script-set GML file)
• sfgml_next: whether targeting GMS2.
• Target GM version is now mentioned in the timestamp header (which can be disabled via -D sfgml_timestamp=false)

Changes:

• sfgml_version is now in GM-style format (e.g. "1.4.1763" or "2.2").

Fixes:

• Fixed (a == b) == c compiling incorrectly (not enough parentheses in generated code).
• Fixed an occasional issue with postfix inline ++ being printed as += 1.
• Fixed a few mismatches in gml.net.*  and asset externs.
• The extension now prefers array_copy over copy-on-write trick because there's this strange YYC bug.
• Fixed @:nativeGen enums reporting field paths ("my_enum_field") instead of names ("field") for getName.
• Fixed SfEnumTools.setTo crashing on nativeGen enums in debug mode.
• Fixed js.Boot not having a std-prefix.
