fee858271c Fix the frame per second counter when using refresh_full_speed 
After commit 575665994a we need to explictly schedule a repaint,
so that we draw and call `measure_frame_rendered`.

e017d5118b Wasm GL backend: use a <input> element so it show the keyboard on mobile 
cc #215

Handle Input event from the input directly instead of going through winit
for the TextInput.

Note that this doesn't handle the composition event well, so the text is
only considered written when it is accepted

MCU: fix text being cut in the printer demo sometimes being cut off (#1083) 
* MCU: fix text being cut in the printer demo sometimes being cut off

When a text element is rendered at exactly the width it reports,
then last letter would be cut off.

* Adjust elision test

d97710f3f9 Implement correct opacity for the GL backend 
This also separates the blend-to-screen part of render_layer into a
helper function, as that will be useful in the future with public layer
elements.

Relates to #725

91b3765e97 Improve method naming in ItemRenderer 
Use `visit_` for the pattern where the trait offers a default implementation that calls other
methods to do the actual work.

f04f0a3e48 GL backend: use direct layers for non-rectangular clips 
Delegate the decision how to implement the Clip element entirely into the backend,
where the GL backend can now explicitly render
children into a layer, instead of the hack with a layer in the renderer's
state and the extra save/restore pair.

6a6a26569d Add support for rendering complex clip paths into cached layers 
If the renderer supports it, clip elements with a complex clip render
the sub-tree into a cached layer.

75949e702c Prepare item rendering for children self-handling 
The render function now takes a self_rc and returns a enum that permits
the implementation to handle rendering of children on its own and
thus make the caller skip that traversal step.

fd2d82e0a3 Flickable: adjust the thresholds 
There must be a high enough threshold because the driver
of our screen is fuzzy and report changing numbers. We
don't want to be moving the Flickable too fast.

c94c223c3b Simplify item rendering loop 
Instead of using the generic visitor, call `visit_children_item` directly on the Component.

This way we avoid the RefCell for the renderer and this will make it
easier to introduce items that decide to render the children themselves, with
their own property tracker.
