The default and example GLSL shaders included in this repository are outdated and dysfunctional.

[Asmageddon]

They do not work as either examples of or functional --window-shader-fg shaders, and the shader named compton-default-fshader-win.glsl is most definitely not the actual default shader as of present day picom.

i removed compton-default-fshader-win.glsl and compton-fake-transparency-fshader-win.glsl in 6996198 to avoid confusion.

an up-to-date default shader can be found in the man page in the "shader interface" section. i think it's fine to have it there. @yshui, what do you think?

as for example shader... well, we have a place for users to submit their shaders, though shaders there may be outdated.
