/**
 * rsvg-features:
 *
 * Check for the version of librsvg being used.
 *
 * Librsvg provides a few C macros that C and C++ programs can use to
 * check the version being used at compile-time, that is, the API that
 * the program expects to have.  This is useful for programs that need
 * to conditionally compile code with `#ifdef` blocks
 * depending on the version of librsvg that may be available during
 * compilation.
 *
 * Librsvg also provides a few global constants that can be used to
 * check the version of librsvg being used at run-time.  This is
 * useful to know which version of librsvg is actually being used on
 * the system where the program is running.

/**
 * LIBRSVG_MAJOR_VERSION:
 *
 * This is a C macro that expands to a number with the major version
 * of librsvg against which your program is compiled.
 *
 * For example, for librsvg-2.3.4, the major version is 2.
 *
 * C programs can use this as a compile-time check for the required
 * version, but note that generally it is a better idea to do
 * compile-time checks by calling [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/)
 * in your build scripts.
 *
 * Note: for a run-time check on the version of librsvg that your
 * program is running with (e.g. the version which the linker used for
 * your program), or for programs not written in C, use
 * `rsvg_major_version` instead.
 */

/**
 * LIBRSVG_MINOR_VERSION:
 *
 * This is a C macro that expands to a number with the minor version
 * of librsvg against which your program is compiled.

 * For example, for librsvg-2.3.4, the minor version is 3.
 *
 * C programs can use this as a compile-time check for the required
 * version, but note that generally it is a better idea to do
 * compile-time checks by calling [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/)

/**
 * LIBRSVG_MICRO_VERSION:
 *
 * This is a C macro that expands to a number with the micro version
 * of librsvg against which your program is compiled.
 *
 * For example, for librsvg-2.3.4, the micro version is 4.
 *
 * C programs can use this as a compile-time check for the required
 * version, but note that generally it is a better idea to do
 * compile-time checks by calling [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/)

 * Note that this a compile-time check for C programs.  If you want a
