• New rotation functions:
  • glm_rotate_at: rotate around point
  • glm_rotate_atm: make rotation around point
  • glm_quat_rotate_at: rotate around point using quaternion
  • glm_quat_rotate_atm: make rotate around point using quaternion
• New mat4 multiplication function
  • glm_mul_rot: multiply matrix with rotation matrix
  • use this function for glm_rotate and glm_quat_rotate functions
• Drop scale1, rotate_ndc transform functions
• updates docs:
  • add clarifications for affine transforms
  • add troubleshooting
• add some tests for affine transforms and for mat3
