* The GPU API uses a left-handed coordinate system, following the convention
* of D3D12 and Metal. Specifically:
*
* - **Normalized Device Coordinates:** The
* lower-left corner has an x,y coordinate of `(-1.0, -1.0)`. The upper-right
* corner is `(1.0, 1.0)`. Z values range from `[0.0, 1.0]` where 0 is the
* near plane.
* - **Viewport Coordinates:** The top-left corner has an x,y
* coordinate of `(0, 0)` and extends to the bottom-right corner at
* `(viewportWidth, viewportHeight)`. +Y is down.
* - **Texture Coordinates:**

* If the backend driver differs from this convention (e.g. Vulkan, which has
* an NDC that assumes +Y is down), SDL will automatically convert the
