Render-level scissoring. This is passed down to your render function but not used for CPU-side coarse clipping. Prefer using higher-level ImGui::PushC

Get into the columns background draw command (which is generally the same draw command as before we called BeginColumns)

FIXME: Remove the == 0.0f behavior?

Push a given id value ignoring the ID stack as a seed.

FIXME: This may incur a round-trip (if the end user got their data from a float4) but eventually we aim to store the in-flight colors as ImU32

We don't use g.FontSize because the window may be != g.CurrentWindow.

Deferred removal, avoiding issue with changing vector while iterating it

Prepare the data for rendering so you can call GetDrawData() (As with anything within the ImGui:: namspace this doesn't touch your GPU or graphics API

Render an arrow aimed to be aligned with text (p_min is a position in the same space text would be positioned). To e.g. denote expanded/collapsed stat

Render an arrow. 'pos' is position of the arrow tip. half_sz.x is length from base to tip. half_sz.y is length on each side.

Helper for ColorPicker4() NB: This is rather brittle and will show artifact when rounding this enabled if rounded corners overlap multiple cells. Call

Tip: pass a non-visible label (e.g. "##hello") then you can use the space to draw other text or image. But you need to make sure the ID is unique, e.g
