Some devices don't support floating point FBOs even though they
support OpenGL ES 3. Check support by creating a FBO and fail early
if no support is found.

I found a convincing use case: stopping asynchronous activities
while paused. A follow up change will rename the stages and add
an example.
This reverts commit f9840b0963.
I'm not convinced the API is right. For exmaple, an event that
notifies a program when to save its state is both smaller and
might be sufficient.

It doesn't seem worth the trouble: images must be scanned for
alpha != 1 and GPUs don't like RGB formats. Use RGBA always.

WebGL use opaque values for object handles, not integers. To ensure
portability, wrap handle types with a struct.

Pros:
- Much less per-frame garbage
- Allow future preprocessing of ops while building it
- Much fewer interface calls and pointer chasing
- Allow future serialization of ops for remote rendering
Cons:
- Slightly clumsier API

For some reason, the CADisplayLink.paused property didn't work on
iOS 10 but does on iOS 12. Use addToRunLoop and removeFromRunLoop
instead.

It turns out we already support multiple windows on Android: when
the activity is recreated.

Replace it with a dummy event send on the synchronous event channel;
a bit of cleverness for a simpler API.

We used to buffer input events to allow for batch processing
multiple events before redrawing. Now that redraws are scheduled to
run after the native event queue is empty, buffering is no longer
necessary.

gioui.org/ui was renamed from gioui.org/ui/ui before the release,
but the import order wasn't changed accordingly.

Gio doesn't support multiple windows anyway, so get rid of the
app.Windows channel and use NewWindow call for the mobile platforms
as well.
