Function push_vec4 

pub fn push_vec4(out: &mut Vec<f32>, x: f32, y: f32, z: f32, w: f32)

Appends four f32 values to out, reusing its capacity when it already covers the write.

Arguments

• &mut Vec<f32> - The destination, which keeps its capacity.
• f32 - The x component.
• f32 - The y component.
• f32 - The z component.
• f32 - The w component.
