Tracking the version under one `-prerelease` channel allows other packages to depend on `^0.1.0-prerelease` for the most up to date version.
Track the git sha for the release in package.json
Reuse the json package needed for writing the sha to retrieve the package.json version field
If another package wants to import `src/index.js`, it needs to replicate the loader config in `webpack.config.js`. To avoid this, package the module in `dist.js` and set that as the module to require.
I changed `main` to point to this so that other packages can just `require('scratch-blocks')`, but it would also work for our purposes to add `"webpack": "./dist.js"` if we want to keep `src/index.js` as `main`.
RenderWebGL{Local,Worker} class methods return Promise instances from
all methods returning a value. This makes the API consistent from a
Web Worker vs. the local page, and also allows the possibility of
asynchronous render queries in the future.
The build generates a new output set called `render-webgl-worker`, meant
to be imported from a web worker. This exposes the `RenderWebGLRemote`
class to facilitate communication with the renderer using `postMessage`
and `onmessage`.
Only a few messages are implemented so far, but it's enough to run the
demo page.
Drawable now creates its own temporary texture upon construction. This
1x1 transparent texture is ready immediately and is replaced once a real
skin is loaded. This slightly simplifies some of the skin loading code
but more importantly prevents GL errors caused when trying to draw a
Drawable if it hasn't yet created its "real" texture, as in the SVG load
path.
The ability to bitwise-combine draw modes turns out to not be a benefit:
it's not safe to short-circuit drawing in the way that I had intended
because it could change the results of blending. Blending could create a
color that matches a "touching color?" check without that color existing
anywhere else.
- Always take color in unsigned-byte terms.
- Moved tolerance value into a class constant.
- Use the same tolerance in JS color comparison as in the shader.
