fcft_capabilities - available optional library capabilities
#include <fcft/fcft.h>
enum fcft_capabilities fcft_capabilities(void);
fcft_capabilities() returns a bitmask of enabled optional library
capabilities:
enum fcft_capabilities {
FCFT_CAPABILITY_GRAPHEME_SHAPING = 0x1, /* Since 2.3.0 */
FCFT_CAPABILITY_TEXT_RUN_SHAPING = 0x2, /* Since 2.4.0 */
};
fcft can do grapheme shaping (using HarfBuzz), and
fcft_grapheme_rasterize() can be expected to return non-NULL.
fcft can do text-run shaping (using HarfBuzz), and
fcft_text_run_rasterize() can be expected to return non-NULL.
