Function ggez::graphics::push_transform

pub fn push_transform(context: &mut Context, transform: Option<Matrix4>)

Pushes a homogeneous transform matrix to the top of the transform (model) matrix stack of the Context. If no matrix is given, then pushes a copy of the current transform matrix to the top of the stack.

You must call apply_transformations(ctx) after calling this to apply these changes and recalculate the underlying MVP matrix.

A DrawParam can be converted into an appropriate transform matrix by calling param.into_matrix().
