Change list

  • Updates RasterLayer to take in renderPipeline prop, which is either an ImageData (for convenience) or a sequence of RasterModule objects that defines a "render pipeline"
  • Modify MeshLayer subclass of SimpleMeshLayer to use our custom fragment shader, which removes the hard-coded sampler2D normalized texture uniform.
  • Creates initial raster modules:
    • CreateTexture: creates a normalized texture and sets it to the variable color
    • FilterNoDataVal: discards pixels that equal a nodata value
    • Colormap: applies a colormap given the value in the first channel of color
  • Update example apps to use latest module system

Closes #92

// We initialize color here before passing into DECKGL_FILTER_COLOR

This still assumes that color will be a unorm vec4. Maybe we'll want to also allow the parameter into DECKGL_FILTER_COLOR to be a uvec4 or an ivec4?
