Ugh. qemu-arm port build and tests failing:

Trigraphs? Seriously? The 1970s are calling and they want to force us to accommodate their crazy keyboards.

Will alter test to not generate output that contains repeated question marks...

If anyone wants to know what the result of this is. It looks like this:

This screen is seriously tiny, so doubled-up text allows it to be read from a distance instead of having to squint at it up close.

Made this patch more flexible by switching to specifying the font size (in pixels) instead of an integer scaling factor. This both allows for drawing text at effective non-integer scales, but also means that a future version could select an alternative built-in font for drawing larger text. Drawing text will be slightly slower with this version due to increased bit twiddling and less scope for short-cutting out of the Y loop.

Related PR: #3583 Simple font size scaling for framebuf

How is this PR coming along? We love the idea of increasing accessibility and usability for small displays. If we're taking votes, I'd vote for a keyword size argument.

As an aside, we've received interest in our forums (thread) at Core Electronics for variable font sizes.

At the moment this PR doesn't seem to have generated sufficient interest to get mainline attention.

Since I always build my own MicroPython these days, I just roll this patch into my production branch; so I'm committed to continuing to support it for the foreseeable future.

We featured this PR in this week's episode of The Factory - our fortnightly engineering catchup.

+1 to see this implemented. Great work @jonathanhogg and hopefully @dpgeorge can assist,

See also #8987. It would be good to see some updates to framebuf.

Rebased to 4903e48 and fixed for renamed function argument.

This is a "Good Idea". +1 from me :)

Any news on whether the sizing feature is going to be present in the upcoming micropython version?

This is an automated heads-up that we've just merged a Pull Request
that removes the STATIC macro from MicroPython's C API.

See #13763

A search suggests this PR might apply the STATIC macro to some C code. If it
does, then next time you rebase the PR (or merge from master) then you should
please replace all the STATIC keywords with static.

Although this is an automated message, feel free to @-reply to me directly if
you have any questions about this.
