This will be easier to understand for the user and will be easier to transform.

This is necessary for making spotlights, sirens, etc.

This will make the renderer more versatile and allow for better UI.

Use rusttype and adapt the example they have there

Not sure the reflections are working properly, make an example to test this. Also, probably write some special test code to visualize better what is happening

Include common practices mistakes recommendations etc.

The camera needs to be changeable by the user

The renderer loop creation process should be made simpler as the "RequestRedraw" event is the only one that needs to be edited by the user.

Add cylinder

This would be a more general version of masks where a framebuffer is made and two objects are drawn on top of each other with a user-defined mix function after rendering to the framebuffer the framebuffer is drawn to the main framebuffer.

rotations seem to be broken

In order to more accurately simulate reflections there should be a render option to blur the reflections.

Problem

When the camera is close to the scene the reflections don't always all land on the scene. This results in a portion of the surface having no reflections

Proposed Solution

Add a render setting to add an additional rendering area around the camera. This would allow reflections to land on offscreen surfaces.
A visual example of what this would look like:

The reflections in the test are not behaving as expected

We should see it be skewed, but instead it seems to be intersecting with it's own color rather than bouncing and intersecting with another pixel.

draw_all is a mess in its current state, it needs to be broken up into a couple of functions.

A video would better help show what the renderer does.

Make an animation object that can parse sprite sheets
