// NOTE: In real compositor mouse location should be mapped to a new window size
// For example, you could:
// 1) transform mouse pointer position from compositor space to window space (location relative)
// 2) divide the x coordinate by width of the window to get the percentage
// - 0.0 would be on the far left of the window
// - 0.5 would be in middle of the window
// - 1.0 would be on the far right of the window
// 3) multiply the percentage by new window width
// 4) by doing that, drag will look a lot more natural
//
// but for anvil needs setting location to pointer location is fine
