Move "@synthesize nameUsedToInstantiate" to within
"#ifdef ENABLE_GLOBAL_IMAGE_CACHE_FOR_SVGKIMAGE_IMAGE_NAMED"
block. When ENABLE_GLOBAL_IMAGE_CACHE_FOR_SVGKIMAGE_IMAGE_NAMED
is not defined this property is not defined in the header file.
Revert #define change for pull request to SVGKit/SVGKit
Change #ifdef's for ENABLE_GLOBAL_IMAGE_CACHE_FOR_SVGKIMAGE_IMAGE_NAMED to work as expected.

The expected behaviour is that the #if'd code will compile only when
ENABLE_GLOBAL_IMAGE_CACHE_FOR_SVGKIMAGE_IMAGE_NAMED is set to 1. Thus,
to make the code compile as expected all the #ifdefs were changed to #ifs.
