TINYGL: Expect colorKey in the same pixel format as surface.

Browse source 
So caller does not have to depend on the pixel format used internally to
BlitImage.
Update callers which do request for color keying (GRIM/EMI only).
Also, remove a special-casing of transparent color when converting image
format which sets a color in a packed format independent from actual
destination format.
Also, in GfxTinyGL::createTextObject, prefer changing invisible colorKey
value than actually-visible color.
