TODO: - [ ] automatically add directional light for sun, remove that - [ ] check if resource creation modifies state - [ ] how vulkan binds textures to uniforms and framebuffers? - [ ] move SSAO init to pex-fx/ssao - [ ] move debug drawing to a separate file Context state mapping to Command properties ### Possible Context states and equivalent Command properties 2016-06-23 If I rename color to clearColor and depth to clearDepth i can get rid of `createClearCommand` all together Questions: - would it be good idea to replace viewport: [l,r,b,t] with [x,y,w,h]? What do regl and THREE.js do? - framebuffer attachments are ugly ```javascript DEPTH_BIT setDepthTest -> depthTest : Boolean setDepthMask -> depthMask : Integer setDepthFunc -> depthFunc : Enum setClearDepth -> clearDepth : Integer COLOR_BIT setClearColor -> clearColor setColorMask -> colorMask : [r:Number, g:Number, b:Number, a:Number] STENCIL_BIT setStencilTest -> stencilTest : Boolean setStencilFunc -> stencilFunc : ? setStencilFuncSeparate -> stencilFuncSeparate : ? setStencilOp -> stencilOp : ? setStencilOpSeparate -> stencilOpSeparate : ? setDepthRange -> depthRange : ? setPolygonOffset -> polygonOffset ?
