VERSION 3.6: procedural textures and new shapes

This update introduces procedural textures for primitives (colormaps, bumpmaps, material maps and emission map) and comes with some new shapes, both as primitives and as DEcombinate formulas. Also, a few bugs have been fixed.

Happy rendering!

Complete changelog:
VERSION 3.6.2316 (12.04.2026):
- mandelbro3d:
- created Turbulence-procedural-texture (SWAN-1111)
- created Voronoi-procedural-texture (SWAN-1112)
- created Wood-procedural-texture (SWAN-1113)
- also allow to use image maps as texture (SWAN-1114)
- implemented material-textures for primitives (SWAN-1117)
- implemented emission-textures for primitives (SWAN-1118)
- fixed: the visible switch did not work for fractals inside hybrids (SWAN-1084)
- created example scenes for procedural textures (SWAN-1119)
- fixed: sometimes the gizmo-display is permanently deactivated and can not activated
again (SWAN-1120)

VERSION 3.5.2307 (12.04.2026):
- mandelbro3d:
- created procedural texture system to be used for primitves (SWAN-1106)
- created Checkerboard-procedural-texture (SWAN-1107)
- created Brick-procedural-texture (SWAN-1108)
- created Grid-procedural-texture (SWAN-1109)
- created Marble-procedural-texture (SWAN-1110)
- implemented color-textures for primitives (SWAN-1115)
- implemented bump-textures for primitives (SWAN-1116)
- renamed "Work Budget" into "Quality Budget" which is more intuitive (SWAN-1104)
- renamed "Dispatch Budget" into "Steps per Pass" (SWAN-1105)

VERSION 3.4.2298 (11.04.2026):
- mandelbro3d:
- added Gyrosphere-primitive (SWAN-1095)
- added Rhombic-Dodecahedron-primitive (SWAN-1096)
- added Hyperboloid-primitive (SWAN-1097)
- added Torus Knot-primitive (SWAN-1098)
- fixed CogOrbitTrap-formula (inner radius shrinks the out radius rather than
creating a hole in the center of the shape) (SWAN-1099)
- rename the parameter "Max Trap Dist" of all DEcombinate-formulas into "Smoothness"
and chose a better default value (SWAN-1100)
- using the rotate gizmo sometimes resets position to default position which makes
it hard to use (SWAN-1101)
- automatically create/update keyframes when moving/rotating objects using gizmos (SWAN-1088)
- fixed: glass-material: glass-color has no effect (SWAN-1102)
- set default Menger Iterations in the MengerPyramid-formula to 2 (SWAN-1103)

VERSION 3.3.2288 (10.04.2026):
- mandelbro3d:
- added GyrosphereOrbitTrap-formula (SWAN-1090)
- added HyperboloidOrbitTrap-formula (SWAN-1092)
- added RhombicDodecOrbitTrap-formula (SWAN-1093)
- added TorusKnotOrbitTrap-formula (SWAN-1094)
- the new julia-mode-controls are now hiodden for IFS and Menger formulas,
because they have no effect here (SWAN-1081)
- removed the generic "Julia W"-parameter as only a few formulas use this parameter
and have their own parameter (SWAN-1082)
- when entering text into fields, also the shortcuts for the fractal viewport
are triggered (SWAN-1085)
- automatically create/update keyframes when moving/rotating camera using gizmos (SWAN-1087)
- fixed ConeOrbitTrap-formula (produces additional disc) (SWAN-1089)
