Hugo Locurcio ed7347d73d Improve the procedural geometry class documentations
This references Godot's winding order at the top of every
procedural geometry class, as well as referencing other classes
within a given geometry class.

A warning about ImmediateGeometry3D performance was also added.

Draws simple geometry from code.
</brief_description>
<description>
Draws simple geometry from code. Uses a drawing mode similar to OpenGL 1.x.
See also [ArrayMesh], [MeshDataTool] and [SurfaceTool] for procedural geometry generation.
[b]Note:[/b] ImmediateGeometry3D is best suited to small amounts of mesh data that change every frame. It will be slow when handling large amounts of mesh data. If mesh data doesn't change often, use [ArrayMesh], [MeshDataTool] or [SurfaceTool] instead.
[b]Note:[/b] Godot uses clockwise [url=https://learnopengl.com/Advanced-OpenGL/Face-culling]winding order[/url] for front faces of triangle primitive modes.

<description>
Begin drawing (and optionally pass a texture override). When done call [method end]. For more information on how this works, search for [code]glBegin()[/code] and [code]glEnd()[/code] references.
For the type of primitive, see the [enum Mesh.PrimitiveType] enum.
