This is the version number macro for the current SDL_image version.
Defined in <SDL_image.h>
#define SDL_IMAGE_COMPILEDVERSION \
SDL_VERSIONNUM(SDL_IMAGE_MAJOR_VERSION, SDL_IMAGE_MINOR_VERSION, SDL_IMAGE_PATCHLEVEL)
In versions higher than 2.9.0, the minor version overflows into the thousands digit: for example, 2.23.0 is encoded as 4300. This macro will not be available in SDL 3.x or SDL_image 3.x.
Deprecated, use SDL_IMAGE_VERSION_ATLEAST or SDL_IMAGE_VERSION instead.
