<-- 'border_col' was removed in favor of ImGuiCol_ImageBorder. If you use 'tint_col', use ImageWithBg() instead. OBSOLETED in 1.91.0 (from July 2024)

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)

If you want to scale an existing font size! Read comments in imgui.h!

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

ATTENTION THIS IS IN LEGACY LOCAL SPACE.

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

EXPERIMENTAL: DO NOT USE YET.

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:: namespace this doesn't touch your GPU or graphics AP

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

Render a rectangle shaped with optional rounding and borders

FIXME: Cleanup and move code to ImDrawList. - Before 2025-12-04: RenderRectFilledRangeH() with 'float x_start_norm, float x_end_norm` <- normalized

Default clip_rect uses (pos_min,pos_max) Handle clipping on CPU immediately (vs typically let the GPU clip the triangles that are overlapping the clip

Another overly complex function until we reorganize everything into a nice all-in-one helper. This is made more complex because we have dissociated th
