bugfix: clipping in line and manhattan mode

Dependencies

• [2] HWPK4SMP new mode: manhattan
• [3] Z2CJVAPV lighter border for figures
• [4] YHQC72JX slightly tweak boundary between concerns
• [5] EFMLTMZG bugfix: restrict strokes to the drawing they started in
• [6] ZD63LJ2T bugfix: keep the click to create a new drawing from creating a new shape in the drawing
• [7] MNWHXPBL more lightweight; select just the stroke at the mouse
• [8] O2UFJ6G3 switch from freehand to just straight lines
• [9] KCIM5UTV revert: back to freehand
• [10] XX7G2FFJ intermingle freehand line drawings with text
• [11] OTIBCAUJ love2d scaffold
• [12] JVRL5TWL store device-independent coordinates inside drawings
• [13] JCSLDGAH beginnings of support for multiple shapes
• [14] G77XIN7M selecting a stroke
• [15] IFGAJAF7 add a level of indirection to vertices of shapes
• [*] 3XD6M3CF refactor
