rect
Specifies the [left, bottom, right, top] rectangle offsets in normalized texture units (0-1), relative to the lower-left corner of the texture.
This command will set the inner border rectangle of the texture in normalized (0-1) units. The border rectangle is used by certain texture quad display modes (
<node3d>.setTexQuadDisplayMode) to determine the corners of the texture.
The default border rectangle is
[0.5, 0.5, 0.5, 0.5], which corresponds to the center of the image.
