@hechtus This also fixed login issues for me, is there anything preventing merging?

If this is still being worked on, I suspect that the issue is that the texture only updates data on the GPU if a `_dirty` flag is set: https://github.com/processing/p5.js/blob/05c93858bcf2ed8f7b1c4362cd459c8312369112/src/webgl/p5.Texture.js#L238 ...but...

Hi! You could use `scale(1, -1)` before drawing to flip the y axis. Would that solve your problem?

@DavidKozdra I think your issue is that just using scale keeps the origin in the same spot. Do you expect the origin to be in the bottom left? if so,...

When drawing your image, you can temporarily mirror the canvas back again: ```js push() scale(1, -1) image(yourImage, 0, 0) pop() ```

Also for completeness, @DavidKozdra one other option available to you is to use p5's `applyMatrix` function ([documentation here](https://p5js.org/reference/#/p5/applyMatrix)) with the same parameters you provided to avoid having to go through...

I looked into this a little bit to see what it would involve. Our tesselation uses libtess, and I've found another I'm not 100% sure this is correct but I've...

Hi, I've been working a lot with p5's WebGL innards recently and would be interested in helping out in that section! I see it's already well covered with GSoC but...

Thanks for opening this! I can look through the code at some point in the near future and see if there are cases where we could be storing values in...

Sorry it took so long to get back to this! Right now, if you make a `p5.Geometry` once and never update it, performance should currently be good, as it won't...
