Helper for ColorPicker4()

Note: as with every ImDrawList drawing function, this expects that the font atlas texture is bound.

This is already called while stepping. The ONLY reason you may want to call this is if you passed INT_MAX to ImGuiListClipper::Begin() because you cou

Scrolling happens only in the central section (leading/trailing sections are not scrolling)

Called in TableSetupColumn() when initializing and in TableLoadSettings() for defaults before applying stored settings. 'init_mask' specify which fiel

Clear and initialize empty settings instance

Adjust flags: default width mode + stretch columns are not allowed when auto extending

Store ImGuiTreeNodeStackData for just submitted node. Currently only supports 32 level deep and we are fine with (1 << Depth) overflowing into a zero,

Initialize before use in a new frame. We always have a command ready in the buffer. In the majority of cases, you would want to call PushClipRect() an

This is used by ImGui::PushFont()/PopFont(). It works because we never use _TextureIdStack[] elsewhere than in PushTexture()/PopTexture().
