Update slider_float call for imgui v1.78+

[cubicibo]

Imgui handles slider differently starting v1.78 onwards, depreciating entirely the power argument. This PR updates the calls for the new imgui API.

Apps running on both pyimgui@master (2022/04/04) and pygame are still broken. Those will work again with the upcoming v2.0. Combined with this PR, imgui_datascience can still be used with the latest version of these libraries.

Thanks a lot! I will study this tomorrow.

Thanks again for this PR.

Yes, I hope this is solved quickly.

I tried your version an it works. However, the flag ImGuiSliderFlags_Logarithmic is a good replacement (since we want k to vary slowly inside [0,1])
Would you mind updating your PR to include flags=1<<4 + 1<<5 (i.e ImGuiSliderFlags_AlwaysClamp | ImGuiSliderFlags_Logarithmic).

I an currently working on a tool which is an adaptation of this for C++. It is called immvision (which stands for immediate vision). I hope to publish it in the next weeks.
