/*!
* pixSaveTiledWithText()
*
* Input: pixs (1, 2, 4, 8, 32 bpp)
* pixa (the pix are accumulated here; as 32 bpp)
* outwidth (in pixels; use 0 to disable entirely)
* newrow (1 to start a new row; 0 to go on same row as previous)
* space (horizontal and vertical spacing, in pixels)
* linewidth (width of added outline for image; 0 for no outline)
* bmf (<optional> font struct)
* textstr (<optional> text string to be added)
* val (color to set the text)
* location (L_ADD_ABOVE, L_ADD_AT_TOP, L_ADD_AT_BOT, L_ADD_BELOW)
* Return: 0 if OK, 1 on error.
*
* Notes:
* (1) Before calling this function for the first time, use
* pixaCreate() to make the @pixa that will accumulate the pix.
* This is passed in each time pixSaveTiled() is called.
* (2) @outwidth is the scaled width. After scaling, the image is
* saved in the input pixa, along with a box that specifies
* the location to place it when tiled later. Disable saving
* the pix by setting @outwidth == 0.
* (3) @newrow and @space specify the location of the new pix
* with respect to the last one(s) that were entered.
* (4) All pix are saved as 32 bpp RGB.
* (5) If both @bmf and @textstr are defined, this generates a pix
* with the additional text; otherwise, no text is written.
* (6) The text is written before scaling, so it is properly
* antialiased in the scaled pix. However, if the pix on
* different calls have different widths, the size of the
* text will vary.
* (7) See pixSaveTiledOutline() for other implementation details.
