Capture Windows text shaping and glyph rasterization for the shared text model.

```yh
external thing graphicsWindowsTextLineGeometry
```

- int utf16Length: Stores utf16 length as int.
- int trailingWhitespaceLength: Stores trailing whitespace length as int.
- int newlineLength: Stores newline length as int.
- int heightQ26_6: Stores height q26 6 as int.
- int baselineQ26_6: Stores baseline q26 6 as int.
- bool isTrimmed: Stores is trimmed as bool.
- graphicsWindowsTextLineGeometry(int utf16Length, int trailingWhitespaceLength, int newlineLength, int heightQ26_6, int baselineQ26_6, bool isTrimmed): Graphics windows text line geometry.
- ValidationIssue(text source) returns text: Validation issue.
- Snapshot() returns text: Snapshot.

## Use graphicsWindowsTextLineGeometry

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using graphics.text.windows

// Capture Windows text shaping and glyph rasterization for the shared text model.
graphicsWindowsTextLineGeometry sample = graphicsWindowsTextLineGeometry(1, 1, 1, 1, 1, true)
Console.Log(Text.From(sample.utf16Length))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.graphics_text_windows__graphicswindowstextlinegeometry"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "graphics.text"
version = "0.1.0"
path = "../../../yeho/packages/graphics/text"

[[dependencies]]
package = "graphics.text.windows"
version = "0.1.0"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/graphics.text.windows--graphicsWindowsTextLineGeometry/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## graphicsWindowsTextLineGeometry.ValidationIssue

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using graphics.text.windows

// Validation issue.
graphicsWindowsTextLineGeometry instance = graphicsWindowsTextLineGeometry(1, 1, 1, 1, 1, true)
text argument_source = "argument source"
text result = instance.ValidationIssue(argument_source)
Console.Log(Text.From(result))

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
