If a Rectangle has a border-radius and clipping, we use an FBO to render
the children and then use femtovg's stencil clipping. If the Rectangle
has a zero width or height, we would end up trying to create a texture
with such dimensions, which produces run-time opengl errors.
We can detect this situation and avoid it early on. The same might happen for shadows.
Fixes#377
When the text selection end follows right after a grapheme that uses less
glyphs than characters, then there may not be a matching glyph with the byte
index, therefore we wouldn't set the selection_end_x and draw incorrectly.
Take the visual tail of the last glyph then.
The cursor navigation left/right (and subsequently text selection) needs
to respect grapheme boundaries. Since we already depend on the
unicode-segmentation crate through femtovg, we might as well use the
functionality for determining grapheme boundaries from there.
The only place where the cursor navigation is allowed to break that is
when using backspace, as that allows the user to break glyph clusters.
We calculate the cursor position as byte offset in the utf-8 encoded string,
while Qt expects an index in the utf-16 encoded QString.
When those differ, the cursor is rendered at the wrong location.
Fixes#363
This requires some gymnastics to get right as the information
need to be passed to the compiler despite having no direct dependency
between the compiler and the runtime or backends.
So use a file in the build directory to tell the default style
cc: #83
Add the icon type explicitly to make it easier to do "eye" based type matching with the cpp! macro.

Sixtyfps uses euclid already, so let's use euclid for float comparisons
as well.
I changed the code to decide whether a number is a positive integer to
make do without a comparison along the way.
The viewer holds the component in a thread_local, so when it is being
dropped, thread_locals are already destroyed.
When an TexInput is focused, it holds a Timer for the blinking cursor,
so when that Timer gets drop'ed, we must not access the thread_local
That's all it is nowadays, it's a wrapper around Rc<Window>. It's not an
alias because we need to also "wrap" it to C++ via cbindgen, but that's
about it.
