Some bad distributions (Debian) apparently are not good enough to have a Pillow version from this decade packaged. Therefore, we need to do it the painful way of prefixing our symbols and refactoring everything to use them. A new header file called "utils.h" has been added for this purpose, and it is included in "overviewer.h". The following macros have been prefixed with "OV_": - MIN - MAX - CLAMP - BLEND - MULDIV255 Additionally, the C extension version was bumped to 56 because 55 was reverted back to 54.
