- add PluginConfig.Background.Styles
- file support, asset management
- opacity, saturation, lightness controls for skybox/image
- coverage controls for image/gradient
- add backgrounds extension with examples
- image handling for build/watch (webpack, cpx)

- skybox, image, horizontal/radial gradient

- bind real texture to tDepth in renderer
- ensure textures are not empty; init as 1x1(x1)

- was broken when used with other postprocessing effects
- expose texture.filter

- only tested for mesh

- lower memory usage
- support for 2^32 vertices in webgl2
- fix rounding issue when creating volume texture

- int textures (webgl2)
- read into Int32Array (webgl2)
- fix ctx.parameters.maxDrawingBuffers (webgl1)
- support setting frag out type (webgl2)

- add texture_half_float, texture_half_float_linear, color_buffer_half_float
- use in multie-sample, gaussian-density

- Move to a separate branch while issues are fixed.

- added .namedComputeRenderables, .namedFramebuffer and .namedTexture
- use for shared resourced instead of storing in closure
- required to have multiple molstar webgl contexts simultaneously

- fix, unset UNPACK_FLIP_Y_WEBGL for 3D tex
- gaussian-volume visual
- fixed, slice visual picking
- fixed, direct-volume renderable picking use depth

- separate pass to check against depth texture
- support precalculated normals
- shading in volume mode
- fixed orthographic projection
- fixed skewed grid (David)
- step size prop
- isosurface picking (needs more work)
