f7cadcba84 examples: Use SDL_GetAudioStreamQueued, not SDL_GetAudioStreamAvailable. 
The "available" side is at the mercy of whatever format the hardware wants,
but we control what we queued.

Fixes #12403.

b95989d14a Fixed sine wave distortion over time. 
Audio distortion after a while caused by loss of precision in dividing a large floating point number resolved by keeping `current_sine_sample` (formelly named `total_samples_generated`) between 0 and freq - 1.

dcc645e413 Fix HTML examples template tabs 
Tab labels now follow their drawer again. Also, to avoid tabs covering
up code or debugging logs, the tab label that's on top (and therefore
not automatically hidden behind the other drawer when that drawer
opens) will now automatically hide itself when the other drawer is
opened.

1d0e28a5b3 Add SDL_RenderDebugTextF & SDL_RenderDebugTextV

the screen without having to format them into a string manually.

1fbb8e1824 examples/audio/04-multiple-streams: Remove drag-and-drop support. 
I'm going to reuse that code for an actual drag/drop example later, but for
simplicity and accessibility of the examples, this is just going to load two
wavs and loop them, so you get the music with a sword-clinking sound mixed
over it.
