Rectangle node

Rectangle {
  SFVec2f size 1 1
  SFVec2f cornerRadius 0 0
}

Display a rectangle centered with the axis and according to the related material with the following specificity when appearance is:

a solid color material: scaling, rotation and transparency are fully supported.
an image texture: scaling and transparency are fully supported.
Rotation is only supported by multiple of 90 degree.
a movie texture: scaling is supported but transparency is not.
If rotation is not zero, video is displayed in landscape mode if supported by the device.

The field cornerRadius allows to display rounded corners for solid rectangle but not with image or video textures.

SFVec2f size 1 1:
The field size is in pixels and is modified by the above transformations.
If any size component is negative, it is replaced by the corresponding image dimension (i.e. size -1 -1 uses actual image dimension).

SFVec2f cornerRadius 0 0:
When cornerRadius has non zero values, the rectangle is rendered with rounded corners.
The above transformations also apply to these values.
Rounded corners are only supported with Material2D (solid color, transparency and filled properties).
