@vitoc checking the reflection change between 2.0.2RC2 and 2.0.3RC1, I notice a minor problem with my PR.

It drops the duplicated constants, but in fact one was define twice, but differently

GMAGICK_REGISTER_CONST_LONG("INTERLACE_NONE", NoInterlace); //Don't interlace image (RGBRGBRGBRGBRGBRGB...)
GMAGICK_REGISTER_CONST_LONG("INTERLACE_NO", NoInterlace);

I have remove the _NO, but it is probably better to keep it and remove _NONE instead (as _NO was used in previous version for PHP 5)

Sorry for not noticing this before
