Direct2D Performance Update

[remaincalm]

hi all

i’ve patched in matt’s proposed changes and they appear to have 100% resolved the host freeze issues i was seeing when multiple instances of plugin editors were onscreen at once

here’s an unlisted video showing the dramatic improvement. the improvement is also present in my more complex “real” plugins.

before/after matt's direct2d-2025 patch (unlisted)

thanks, matt!
