on line 85 there is an error when tests are run with libc++ hardness mode with the debug setting
on line 82 we reserve space for the vector this does not change n though so when
we access it on line 85 there is an error n=0, to fix this we reserve and initalize the vector

- Thick lines were drawn by expanding a line to 2 triangles stacked on their longest side using a geometry shader. When coloring by cell scalars, this worked everywhere except on apple silicon.
- There seems to be a bug related to geometry shaders in Apple's OpenGL driver that caused thick lines to not correctly pick up cell colors.
- It looks like the value written to `gl_PrimitiveID` is overwritten implicitly by `EmitVertex` and incremented each time a vertex is emitted from the geometry shader.
- This commit works around it by fixing the usage of `gl_PrimitiveID` in fragment shader when drawing thick lines.

(cherry picked from commit 62466099)

Common cases:
- Cell array only contains triangles
- Cell array only contains triangles, and connectivity type is uint32

SetTimer is not precise. It's replace by CreateTimerQueueTimer.
This new API is also supporting one-shot timers so it's not necessary
to kill the timer anymore.

This mapper uses GPU texture acceleration to draw labels at much
higher frame rates. When hundreds or thousands of labels are on
screen at one time, existing mappers can drop below 1 fps. This
acceleration is designed to render the same number of labels at
over 60 fps so a user can label many points while retaining
interactive rotations and animations.

The OSPRay renderer node avoids ambient lighting if there is an existing
ambient light in the scene. However, this would fail if the existing
light was switched off. This new check ensures that OSPRay uses ambient
illumination even if existing ambient light is switched off.

Composite datasets can have both opaque and translucent datasets.
Revert to reporting that they always have opaque datasets to fix
rendering errors where opaque blocks are skipped when translucent
blocks are present.

This code doesn't fit the usage of the VTK_DEPRECATED_IN_X_Y_Z()
macros, but we still want to eventually remove it, so we are
marking it to be removed when deprecated-in-9.5.0 code is removed.

This has been deprecated and will be removed in a future release.
Migrate to kwargs instead.

Found with Xcode 15.4 as a warning.

- This functionality is useful to have even outside `vtkWebGPUPolyDataMapper`.
- This commit lifts it out of the C++ webgpu polydata mapper source file into a separate class.

- This commit separates the functionality into `vtkWebGPUCellToPrimitiveConverter`. The compute shader based cell to primitive conversion routines are helpful even outside the `vtkWebGPUPolyDataMapper`.

Autodetection is done with on-screen rendering turned off, so we
can use this fact to turn off spurious "bad X server" warnings
during autodetection, while keeping the warnings enabled in other
situations.

- This unit test exercises rendering actors that
  embed other actors.

- Lift the member variables from composite polydata mapper to the base class (vtkPolyDataMapper)
