-/**
- * Make a temporary (color) texture image with GLfloat components.
- * Apply all needed pixel unpacking and pixel transfer operations.
- * Note that there are both logicalBaseFormat and textureBaseFormat parameters.
- * Suppose the user specifies GL_LUMINANCE as the internal texture format
- * but the graphics hardware doesn't support luminance textures.  So, we might
- * use an RGB hardware format instead.
- * If logicalBaseFormat != textureBaseFormat we have some extra work to do.
- *
- * \param ctx  the rendering context
- * \param dims  image dimensions: 1, 2 or 3
- * \param logicalBaseFormat  basic texture derived from the user's
- *    internal texture format value
- * \param textureBaseFormat  the actual basic format of the texture
- * \param srcWidth  source image width
- * \param srcHeight  source image height
- * \param srcDepth  source image depth
- * \param srcFormat  source image format
- * \param srcType  source image type
- * \param srcAddr  source image address
- * \param srcPacking  source image pixel packing
- * \return resulting image with format = textureBaseFormat and type = GLfloat.
