This file requires manual maintenance and continuous review, it also changes from day to day moving sponsors from present-to-past and sometimes the other way round.

GitHub already lists the sponsors on the user profile, in a better an more visual way.

I also have doubts this should be a document distributed with raylib sources...

Also using proper functions to seek to start of an audio file.
Removed old comment.

ISSUE: Front buffer and backbuffer have different clear colors, if no `ClearBackground()` is called by user, there is screen flickering on buffers swap.

It's up to the user to call `ClearBackground()` if desired

Reviewed some camera functionality:

 - Reviewed camera swinging (up-down movement)
 - Reviewed camera tilting (left-right movement)
 - Make movement independent of frame-rate
 - removed unneeded variables

NOTE: Camera rotation has some speed issues on first person when fixed 60 fps are used: it moves too fast. Independent framerate movement is not properly implemented.

Dimensions of Rectangle should be casted to int before multiplication,
otherwise there is a risk for underallocation/overallocation of memory.
