Fix Shader for OpenGL ES 2.0 feature set

[s-ol]

• fix use of int/float types
• don't rely in smoothstep

This is what currently causes the issues with the gh-pages /love.js builds.

I'll see what I can do. Wanted to get back into GLSL coding anyway.

[rm-code]

Welp ... @TannerRogalsky was faster :D

[JanWerder]

I still seems to crash

[rm-code]

Yup, same here.

[TannerRogalsky]

@JanWerder @rm-code Please read through that PR. There is another issue.

[TannerRogalsky]

I'm going to provide a 'compatibility' build going forward to avoid issues like this. Performance and file size take a hit but it should be easier to work with. https://github.com/TannerRogalsky/love.js/tree/master/release-compatibility

[s-ol]

Can someone verify that love2d-community.github.io/splashes does now work with the compat love.js?

@S0lll0s I'm getting the following error:

Error: [string "boot.lua"]:432: No code to run
love.js:1 Your game might be packaged incorrectly
love.js:1 Make sure main.lua is at the top level of the zip
love.js:1 stack traceback:

love.js:1   [string "boot.lua"]:432: in function <[string "boot.lua"]:274>
love.js:1   [C]: in function 'xpcall'

[s-ol]

hm, for some reason love.js completely wrecks my browser. Can't even debug this situation right now until I get back home in 2-3 weeks :/

don't rely in smoothstep

smoothstep works fine in OpenGL ES 2's shading language.

@slime73 #12 (comment) :D :D

[s-ol]

So think this is done then?
