The origin of image.Images is the upper left corner. Convert the
ReadPixels result by flipping the image the y-direction.

While here, unexport the Queue and Config fields. The NewContext
cosntructor is shorter, and there is no reason to expose the fields
to accidental mutation.

EGL contexts don't need locking, so their Lock and Unlock methods
are empty. Remove them and add them where necessary instead.

The policy of rendering on a separate goroutine is separate from
the actual rendering. Reflect that by introducing the RenderLoop
type for driving a GPU from a separate goroutine.

Instead of calling from the low level context into the window
for its surface and dimensions, add a Context.MakeCurrent method
that does it directly.
The result is simpler and clearer logic. For example, synchronization
is obviously no longer needed. It wasn't necessary before, but the
reason was unclear.

For Windows:
- Add shift/ctrl/etc modifiers to mouse events, so you can recognize the
difference between "click" and "shift-click".
- Add several allowed punctuation characters as single key events, so
you can (for example) use "." as a hotkey.

it as a Fragment in the window's Context.

Put List.{first|offset|beforeEnd} into a new exported Position slot, and
also export each individually.
Have to put BeforeEnd into the Position slot to support ScrollToEnd
lists.

We already wait for the app to render itself via the "frame ready"
stdout prints. Waiting for the canvas to be ready isn't really necessary
anymore. It helped us while we had to rely on sleeps, but that's no
longer the case.

The js/wasm bug meant that printing to stdout in the e2e app would crash
the runtime, so we couldn't synchronize with the app like in the other
drivers.
Now that the bug is fixed, we can do the same as the other drivers just
fine.

Allows things like "ctrl-{" and ".".
All punctuation is returned as-is, e.g. "!" is "!", not "shift-1", and
"{" is "{", not "shift-[".
Also add the Enter key as a known key (fn-return on my Mac).

The code tried to extract a rounded whole number of pixels while preserving the
fraction. However, it failed to converge for the value 0.5, rounded to 1,
leaving -0.5, rounded to -1, leaving 0.5 and so on.
Drop the cleverness and truncate the values instead.
