Ashley, What we asking is to add an option to draw gamma-incorrect gradient. While gamma-correct may be better in some cases, we also need the simple non-corrected version.
Take OP for example - as I understand, he is creating some sort of graphics editing tool. Future users of this tool will expect to see the same gradient as they get from Photoshop, Illustrator, Corel etc. Gamma-correct gradient in this case will be seen as a bug.
