This is "pixel-accuracy" 2D-shadows.
Shadows compute fully on the GPU's pixel-shaders.
Need GLSL 1.20 (OpenGL 2.1).
Used GLSL-shaders from: http://bitbucket.org/totorigolo/shadows

Story.
I could not write the GLSL-code yourself (my code you find in sources).
Then i I found this video: https://www.youtube.com/watch?v=Liv7BcMYelE
And asked source code from author of video.
Thomas Lacroix (author) give me sources: https://bitbucket.org/totorigolo/shadows
I adapt his GLSL-shaders to LOVE2D, and this is worked.
Thank you Thomas Lacroix.
