+// This function alpha blends a fixed color into a destination scanline, using
+// the formula:
+//
+//     d = s + (((a + (a >> 7)) * d) >> 8)
+//
+// where d is the destination pixel,
+//       s is the source color,
+//       a is the alpha channel of the source color.
+//
+
+// r0 = destination buffer pointer
+// r1 = color value
+// r2 = count
