I was researching a lot about shaders the other night.. I wanted to incorporate blend modes but as far as I can tell, it can't be accessed through shaders. I think this would typically be enabled with opengl calls glEnable() and glBlendFunc() but I couldn't get that to work. Things like GL_BLEND, GL_ONE and other params don't seem to be defined when called in shaders:
https://www.opengl.org/sdk/docs/man/html/glBlendFunc.xhtml
In order to implement blending yourself, you need access to source color and destination color (which I don't think is available).
It is definitely is a part of SFML, is it maybe just not implemented in AM?
