Win32 clipboard implementation We use g.ClipboardHandlerData for temporary storage to ensure it is freed on Shutdown()

Fully unrolled with inline call to keep our debug builds decently fast.

Release the number of reserved vertices/indices from the end of the last reservation made with PrimReserve().

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)

Use ImDrawList::_SetTextureID(), making our shared g.FontStack[] authorative against window-local ImDrawList. - Whereas ImDrawList::PushTextureID()/Po

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
