Detailed Description

A 9-slice panel layer: one BG tilemap and the sheet to stamp from.

The sheet is read in raster order from base_tile:

base+0        base+1        base+2         <- top-left, top, top-right
base+stride   base+stride+1 base+stride+2  <- left, centre, right
base+2*stride …                            <- bottom-left, bottom, bottom-right

stride is the sheet's width in tiles, which is 3 for a bare 9-slice and more when the sheet carries other art in later columns — examples/games/rpg uses a 4-wide sheet whose fourth column holds HUD icons.
