Added exposure pass calculating the bloom/tonemap exposure based on what the eye is seeing 2016-09-18 13:57:22 +00:00
- add layout location decl to all postprocess shaders 2019-03-05 17:55:31 +00:00			`layout(location=0) in vec2 TexCoord;`
- specify fragment output locations in the shader source. OpenGL has been supporting this since version 3.3 and Vulkan requires it so it's the way to go. 2018-06-12 21:52:33 +00:00			`layout(location=0) out vec4 FragColor;`

- read sampler bindings from the shader instead of tagging along a large amount of support data. Works for most shaders, except SSAO. 2018-06-13 13:53:56 +00:00			`layout(binding=0) uniform sampler2D SceneTexture;`
