When applying imagegammacorrect() the alpha channel is now fully retained, instead of being completely lost.

Thx for the patch! Exactly what is needed (gamma correction should not be applied to alpha, for the record) Should be applied to 5.5+,go ahead :) |

I can't merge it myself; I don't have php-src karma. |

I've tested this on Windows 7 and Ubuntu 14.04 (bundled GD lib only).
@pierrejoye @remicollet Please have a look at this PR. The patch seems to be straight forward, and I don't expect it to be a real BC break, because likely nobody used imagegammacorrect() on images with alpha channel (at least without manual correction). At least this might be merged into master for PHP 7.
