84e66ea83026 DPF-Prymula-audioplugins-0.231015-2 prymula <prymula76@outlook.com> parents: diff changeset	175 Then you define one or more paths and sub-paths which describe the shape. The are functions

84e66ea83026 DPF-Prymula-audioplugins-0.231015-2 prymula <prymula76@outlook.com> parents: diff changeset	203 transformation. For example if you set font size to 12, which would mean that
84e66ea83026 DPF-Prymula-audioplugins-0.231015-2 prymula <prymula76@outlook.com> parents: diff changeset	204 line height is 16, then regardless of the current scaling and rotation, the
