port(EterLib): TextBar/DibBar/BlockTexture for uiTip TipBoard/BigBoard

TextBar and DibBar verbatim over the FreeType GDI shim (+GetTextExtentPoint32A);
BlockTexture verbatim except Render, which records the clipped quad as a UI
image of the device CPU texture (UIRenderAddImageNamed). Notices now render;
port.text_bar covers block split, pixels, colour, ClearBar and TipBoard clip.
