Subject: [PATCH] [Image] Validate that ImageDrawRectangleRec is drawing
 entirely inside the image (#3264)

* Add a function to clone a sound and share data with another sound.

* rename items based on feedback

* PR Feedback, use custom unload for sound alias, not variant of normal sound unloading

* sound_multi example

* Validate that image rect drawing is inside the image so we don't overflow a buffer

* remove files that should not have been added.

* remove changes that should not have been

* revert

* adsfasdfsdfsdf
