b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	3 * rcamera - Basic camera system with support for multiple camera modes

b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	5 * CONFIGURATION:

b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	7 * Generates the implementation of the library into the included file.
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	8 * If not defined, the library is in header only mode and can be included in other headers
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	9 * or source files without problems. But only ONE file should hold the implementation.

b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	11 * #define RCAMERA_STANDALONE
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	12 * If defined, the library can be used as standalone as a camera system but some
b55c22cff335 Add interactive infinite canvas prototype MrJuneJune <me@mrjunejune.com> parents: diff changeset	13 * functions must be redefined to manage inputs accordingly.
