GPU APIs require that barrier() calls are dynamically uniform, that is
for every barrier in the code, every shader invocation in a workgroup
must all call it, or all not call it.

The reflected uniform names are for the shader versions that don't use uniform
buffer objects. For UBO shaders, the names won't resolve.
This change adds a panic when shader uniforms are not found, and fixes

The recent changes to the compute shaders have fixed all errors
previously reported by fxc. Switch from dxc to fxc to target shader
model 5.0, supported by Direct3D 11.
Because we know dxc must be available, always build compute shaders even
though the result is not yet used.

Apparently, exec.Command.Output waits for winepath's grandchildren to
exit. However, that may take several seconds if wineserver was started
by winepath.
exec.Command.StdoutPipe works better, in that it is closed when the
winepath process exits.
A similar change may help run the fxc.exe tool under Wine, if that ever
turns out to have the same problem.

Wine tools can be slow to run, so it makes sense to batch their use.
Fortunately, winepath supports resolving multiple paths in one
execution.

F10 has a special meaning on Windows, if the default handler runs the
first key press following F10 will not generate a key.Press event and
if the first key press after F10 is space the window menu will be
opened instead.

Currently, the redraw is called inside js.FuncOf. That PR moves the

The current method (of calling inside the FuncOf) seems to be responsable

Before this change, the two renderers both had special case code for
approximating strokes they don't support natively. This change moves
that conversion to clip.Op.Add, for several reasons:
- The compute renderer no longer need fallback logic and caches for
strokes it doesn't support.
- The approximation logic is slow. Moving it to clip.Op.Add will not
speed it up, but will make the cost easier to spot in profiles. Until all
strokes are supported natively, users can use macros to cache
expensive strokes.
- Reduced garbage: Op.Add takes an op.Ops anyway, and can use that for
storing the approximated stroke outline.

To avoid an import cycle in a future change, internal/stroke can no
longer import op/clip. Move required op/clip functionality to
internal/stroke and duplicate the remaining types.

Both Path.Arc and the internal stroke package needs to support arcs;
this change isolates the approximation computation into a function we
can move to internal/stroke in a follow-up.

Complex strokes are not yet supported in either of the current renderers,
so they are converted to filled outlines in package gpu.
We're about to move that complexity up to the op/clip package, so we're
going to need the converter available from outside package gpu. This
change extracts the conversion code and related types to the separate,
internal package stroke.
No functional changes; a follow-up moves the stroke conversion.
