This updates all the darwin stb libraries to be built as universal
libraries - meaning they contain both Intel and Apple Silicon versions.
This should make these more generally compatible.
Also, add stb_vorbis.a in the same way. Not sure why it was missing
before.
This Darwin-specific target builds each stb library with macOS-specific
options so that the results are universal static libraries that should
work on Intel (x86_64) and Apple Silicon (arm64) machines. They also
should work on macOS 10.12 and above (which should match what Odin
compiles for).
The default Makefile target will build the darwin rule if its invoked on
a macOS machine, otherwise it'll invoke the more general unix target.
Add `print(x, y, text, color, quad_buffer)` version that takes `[]quad`.
(Same internal memory layout as []u8 API, but more convenient for the caller.)
Add optional `scale := f32(1.0)` param to `print` to embiggen the glyph quads.
```odin
// Example for use with vendor:raylib
quads: [999]easy_font.Quad = ---
color := rl.GREEN
c := transmute(easy_font.Color)color
num_quads := easy_font.print(10, 60, TEXT, c, quads[:])
for q in quads[:num_quads] {
tl := q.tl.v
br := q.br.v
color = transmute(rl.Color)q.tl.c
r := rl.Rectangle{x = tl.x, y = tl.y, width = br.x - tl.x, height = br.y - tl.y}
// Yes, we could just use the `color` from above, but this shows how to get it back from the vertex.
// And in practice this code will likely not live as close to the `easy_font` call.
rl.DrawRectangleRec(r, color)
}
```
