f296bec7ca SDL3: Allow overriding scale mode. 
SDL3 features a unique scale mode that is neither nearest nor linear,
that being `SDL_SCALEMODE_PIXELART`, and I want to use it in my
emulator. Dear ImGui prevents this by forcefully overriding the
texture's defined scale mode, so this commit allows Dear ImGui to be
overridden in turn.

Previously the scale mode was hidden within the internal state, but
now it is exposed in the public render state struct.

ocornut#9378 mentions opening an issue if anyone ever wants access to
this internal state, but I think a PR will do better.

e8602501bb Mixed Value: various fixes. (#5518, #5677, #6865) 
- With MixedValue+LiveEdit: a single edit that ends up with same output reports as edited.
- Standardize path sin TempInputscalar(), InputScalar(), InputTextEx().
- Refer to changes in imgui_test_suite, in particular "widgets_datatype_1", "widgets_status_liveedit_off",

Sliders, Drags: adjust ScaleValueFromRatioT() to increase remapping precision (in theory). (#9536) 
Omar: couldn't detect any output difference in test suite with large u64/s64 ranges drag/sliders.
I believe this is entirely theoretical and it's principal value is to shut Linter warnings

fd74775a0d ColorButton: fixed double style alpha multiply. Remove call to GetColorU32() in RenderColorRectWithAlphaCheckerboard() for consistency. (#9511) 
The main fix is the change from GetColorU32() to ColorConvertFloat4ToU32() in calling code.
The change from GetColorU32() to manual multiply in RenderColorRectWithAlphaCheckerboard() is merely for consistency with other ::Render calls.
