A gf_color_t is a generic 32-bit color argument used by the GF library. This type is assumed to be native endian, with the following components:

• red —an 8-bit value specifying red intensity, occuping byte 2 (bits 16-23).
• green — an 8-bit value specifying green intensity, occuping byte 1 (bits 8-15).
• blue — an 8-bit value specifying blue intensity, occuping the least significant byte (bits 0-7))
• alpha — and 8-bit value specifying alpha factor, where applicable. This value occupies the most signifcant byte (bits 24-31).
