Re: [Tuxpaint-devel] SDL2 for the next release for windows?

[Bill K. <nb...@so...>]

Thanks for looking into this and bringing it up, Shin-ichi.

I think like like option B -- SDL2 for Windows10/11, and SDL1 for
older systems, or perhaps simply as an option "if you have trouble".

It may be worth building a beta release of the SDL2-based version
which I can ask users out in the real world to please test out.

(I almost _never_ get feedback from people when I do that, so I'm not
sure it'll work... but who knows?!  We're at nearly 1,000 followers on
Twitter, and over 19,000 "likes" & followers (two different metrics)
on Facebook... though they make it very hard to get any reach without
spending money $$$ >:-( )

I know on Twitter you were suggesting we try for a new release
for our 20th anniversary next month, and we've already got a LOT
of changes stacked up since the last release, back in November! :-)

 * interactive brush spacing option
 * stamp scaling performance improvement
 * circular eraser outline/preview
 * some new polygon shapes
 * improved OSK scaling
 * "apply" button for labels
 * various label bugfixes (:crosses fingers:)
 * Ctrl keyboard shortcut for pipette tool
 * Red/Yellow/Blue color mixer
 * true HSV in color picker
 * two new zoom-y magic tools
 * sorting option for open/slideshow dialogs
 * auto-repeat when click+hold'ing arrow buttons in more places
 * lots of build (mac/win) updates
 * lots of localization updates
 * improved documentation styling
 * various other bugfixes

Whew, it's been a busy 6 months, hasn't it!?  8^o
