Issue #443 wontfix

Request for 'min' and 'max' blend modes via GL_EXT_blend_minmax

Anonymous created an issue

It would be useful for something I'm working on as there isn't any option for using the Z buffer for equivalent functionality.

Currently I'm having to do a lot of canvas swapping which isn't very fast.

Probably not a commonly used feature though.

    The min and max blend equations can be used to implement Photoshop's "lighten" and "darken" blend modes. However, I'm not quite sure what to do with the alpha channel, and min and max aren't available in OpenGL ES 2. :(
