`size_t` as appropriate) - BMP: lessen heap memory usage by only `malloc()`ing a row, not whole file - GIF: lessen heap memory usage by paging (also simplifies some function returns); use standard colour char map - raster: add `raster_malloc()` to fail > 1GB (avoids very large output files that most systems can't handle; also lessens to some degree chances of being victim of OOM killer on Linux) - GUI: printing scale dialog: set maxima on X-dim and resolution to keep scale <= 200
