We will only keep Color_RGB8 and Color_RGBA8. Everything else belongs in the port.

Blocked by #580

move to shipdk

libultraship/include/libultraship/color.h

Lines 10 to 16 in 00c6bcc

	typedef struct {
	uint8_t r, g, b;
	} Color_RGB8;
	typedef struct {
	uint8_t r, g, b, a;
	} Color_RGBA8;

lets ports handle it

libultraship/include/libultraship/color.h

Lines 19 to 42 in 00c6bcc

	typedef union {
	struct {
	#ifdef IS_BIGENDIAN
	uint8_t r, g, b, a;
	#else
	uint8_t a, b, g, r;
	#endif
	};
	uint32_t rgba;
	} Color_RGBA8_u32;
	typedef struct {
	float r, g, b, a;
	} Color_RGBAf;
	typedef union {
	struct {
	uint16_t r : 5;
	uint16_t g : 5;
	uint16_t b : 5;
	uint16_t a : 1;
	};
	uint16_t rgba;
	} Color_RGBA16;
