GDI hooks: In the TextOut and ExtTextOut functions, get the previous color at the provided X, Y coordinates before calling the original function, so we at least have a chance of knowing the correct background color if the text is being drawn in transparent mode. This is necessary to detect highlighted text in some parts of Dragon NaturallySpeaking.

GDIHooks: only call GetPixel if the background color when writing text is transparent. GetPixel can be slow so we want to limit its use.

gdiHooks: no need to check if bkMode is transparent twice.
