Summary	0014734: New preflight warning "use of All color"
Description	"All" color is not a normal color : it doesnt behave as other colors, it doesnt behave as it looks, it might not render as scribus renders it. There should be a toggleable warning when "All" color is used for some user created objects.
Additional Information	AFAICT "All" color is a special PDF color used for technical things as cropmarks. It should not be used as a normal color. I dont know when and why that colors appears listed in scribus UI but since it appears as white in the color list, it can be mistakenly used for white as if it were a normal useable color. In scribus it appears white but depending on the RIP it can be rendered as black. See 0014736 See screenshot further down the comments https://bugs.scribus.net/file_download.php?file_id=9559&type=bug
Tags	No tags attached.

Patch	No
