You don't need shaders for this, you can accomplish such effect by drawing glow effect into sprites, or rendering glow sprites over normal sprites. If you insist on using shaders, you
1) take the base scene image and subtract some value fixed from all color components, multiply the remaining values as appropriate
2) apply blur to the resulting "brightmap texture"
3) render resulting "glow image" over original image
There are specific shaders for that in the "moonshine" pack.

Me and my stuff :3True Neutral Aspirant. Why, yes, i do indeed enjoy sarcastically correcting others when they make the most blatant of spelling mistakes. No bullying or trolling the innocent tho.
