I clearly don't know what I'm doing.

Go to sleep! Think, then type!

Is this fun? Kinda.
...
I should break out the graph papaer and Abrash's Black Book and figure
out WTF I'm doing rather than just noodling around, eh?

Aw, exit() doesn't work?
...
In any event, I can live with esc-to-quit (is there a callback to hook
into?)

But KEY_BACKSPACE doesn't seem to fire?
...
Maybe worth a bug report?

Ha ha! The escape-to-quit behavior...
...
...seems to be baked into the UVM.

Add if..else ladder for keys.
...
I just noticed that I have KEY_BACKSPACE for the exit key rather than
KEY_ESCAPE as I had thought, yet escape key surely does exit the
program!

Escape key exits program.

I don't think this is any better?

Draw chars when you click.
...
Pick a letter at random.
I wasn't checking that the destination values were not less than zero,
which let you click at the top/left edges of the screen and therefore
the carefree_alpha_blend_blit() would try to write to areas outside the
framebuffer. I started to see "zalgol" pixels in the letters, so I'm
guessing the pixel data is getting stored just above the framebuffer,
which makes sense (because that's the order they appear in the source
code and this is a simple system!) When you click at the top of the
screen it was writing pixels in the font data, eh? Then when you click
elsewhere on the screen you get extra pixels with your letterforms and
it looks like Unicode Lovecraft puns.

A sort of blit.

Okay, alright, skipping blank pixels.

We have a character on the screen!
...
It looks like potato because no alpha blending yet, but it's certainly
there! I don't like the spelling of the C code, but who cares? It
works.

A start on draw_char().

Rename anim_callback to draw_background

because that's what it is

This compiles and runs, include font.h but don't call init_font_data() yet.

Drawing pixel per mouse move is slow at 1280x800.
...
So let's just use a smaller screen for now, eh?

Repair damage during mouse move.
...
This is a compromise between updating the screen every frame (which
takes ~60% CPU on my old no-GPU hardware) and repairing damage from e.g.
dragging offscreen and back on, or covering and uncovering the window
with another window.
