Subject: [PATCH] proposed fix: set curr_src.h is to bottom_height before
 drawing bottom edges / corners in SDL_RenderTexture9Grid, to avoid issue
 where inadvertently using top height if the npatch existed on a larger
 texture than the drawn edge would cause too many pixels to be included in the
 bottom part of the render.
