- * One might think that the best value for SP_SCALE24_MAX would be ((1<<24)-1), which allows the
- * greatest possible precision for fitting [0, 1] fractions into 24 bits.
- *
- * However, in practice, that gives a problem with 0.5, which falls half way between two fractions
- * of ((1<<24)-1). What's worse is that casting double(1<<23) / ((1<<24)-1) to float on x86
- * produces wrong rounding behaviour, resulting in a fraction of ((1<<23)+2.0f) / (1<<24) rather
- * than ((1<<23)+1.0f) / (1<<24) as one would expect, let alone ((1<<23)+0.0f) / (1<<24) as one
- * would ideally like for this example.
- *
- * The value (1<<23) is thus best if one considers float conversions alone.
- *
- * The value 0xff0000 can exactly represent all 8-bit alpha channel values,
- * and can exactly represent all multiples of 0.1. I haven't yet tested whether
- * rounding bugs still get in the way of conversions to & from float, but my instinct is that
- * it's fairly safe because 0xff fits three times inside float's significand.
- *
- * We should probably use the value 0xffff00 once we support 16 bits per channel and/or LittleCMS,
- * though that might need to be accompanied by greater use of double instead of float for
- * colours and opacities, to be safe from rounding bugs.
