Draw_ProcessPath takes a flag in b31 of R7, which is otherwise an (aligned) address. This is not compatible with 32bit OSes nor even high-address Dynamic Areas on older OSes. A new API was introduced from Draw 1.17 that uses b25 & 26 of R1 instead. This module provides that API for older modules, such as the one supplied with RO4.37. If a Draw module 1.17+ is available, this module silently kills itself, so it is always safe to load it without having to RMEnsure anything.

If R1 b26 is set then the new API is in use, and the “Output Bounding Box” flag is in R1 b25 instead of R7 b31. Note that this does not change the Draw module itself, so attempting to output a bounding box to a high-bit address will fail with “Invalid address”.
