Proofread and improve the whole class reference
- Document a few more properties and methods
- Add more information to many classes
- Fix lots of typos and gramar mistakes
- Use [code] tags for parameters consistently
- Use [b] and [i] tags consistently
- Put "Warning:" and "Note:" on their own line to be more visible,
  and make them always bold
- Tweak formatting in code examples to be more readable
- Use double quotes consistently
- Add more links to third-party technologies

<brief_description>
3D transformation (3×4 matrix).
</brief_description>
<description>
Represents one or many transformations in 3D space such as translation, rotation, or scaling. It consists of a [member basis] and an [member origin]. It is similar to a 3×4 matrix.

<argument index="0" name="from" type="Quat">
</argument>
<description>
Constructs the Transform from a [Quat]. The origin will be Vector3(0, 0, 0).

<method name="Transform">
<return type="Transform">
</return>
<argument index="0" name="from" type="Basis">
</argument>
<description>
Constructs the Transform from a [Basis]. The origin will be Vector3(0, 0, 0).
</description>
</method>
<method name="affine_inverse">
<return type="Transform">
</return>
<description>
Returns the inverse of the transform, under the assumption that the transformation is composed of rotation, scaling and translation.
</description>

<method name="interpolate_with">
<return type="Transform">
</return>
<argument index="0" name="transform" type="Transform">
</argument>
<argument index="1" name="weight" type="float">
</argument>
<description>
Interpolates the transform to other Transform by weight amount (0-1).
</description>
</method>
<method name="inverse">
<return type="Transform">
</return>
<description>
Returns the inverse of the transform, under the assumption that the transformation is composed of rotation and translation (no scaling, use affine_inverse for transforms with scaling).
</description>
</method>
<method name="looking_at">
<return type="Transform">
</return>
<argument index="0" name="target" type="Vector3">
</argument>
<argument index="1" name="up" type="Vector3">
</argument>
<description>
Returns a copy of the transform rotated such that its -Z axis points towards the [code]target[/code] position.
The transform will first be rotated around the given [code]up[/code] vector, and then fully aligned to the target by a further rotation around an axis perpendicular to both the [code]target[/code] and [code]up[/code] vectors.
Operations take place in global space.

</return>
<argument index="0" name="axis" type="Vector3">
</argument>
<argument index="1" name="phi" type="float">
</argument>
<description>

<members>
<member name="basis" type="Basis" setter="" getter="">
The basis is a matrix containing 3 [Vector3] as its columns: X axis, Y axis, and Z axis. These vectors can be interpreted as the basis vectors of local coordinate system traveling with the object.
</member>
