- * 21.3.2006

- *
- * RLE encoding is dangerous and can be used by attackers by creating special files.
- * We has 'buffer_ptr' and 'buffer_end' variables and buffer_end points to first
- * unaccessible byte in buffer.
- * - If we use 'byte = *(buffer_ptr++) in main loop we must check if
- * 'buffer_ptr != buffer_end', because special or incomplete bmp file can generate
- * segfault (I was writing it, because in RLE we need to read depending count of
- * bytes that depends on requester operation).
- * SOLUTION: Don't read one byte, read two bytes and check.
- * - If RLE teels us than single color length will be larger than allowed, we can
- * stop, because bitmap is corrupted or crawled.
- * SOLUTION: Check for length ('l' variable in RLE) and break loop if it's invalid
- * IMPROVEMENTS: We can stop checking if 'x' is out of rangle, because it never be.
- * - In RLE4 use one bigger loop that fills two pixels. This is faster and cleaner.
- * If one pixel remains (the tail), do it on end of the loop.
- * - If we will check x and y (new line and skipping), we can't go outsize imlib
