v3.2 Tasks

[erincatto]

• Cable Joints
• Gears
• Serialization
• Rollback
• Rounded rectangle mover
• Compare with fixed rotation mover
• Extend character sample with tile-based
• Report contact points in local space? So they can be resolved at the final transform.
• Text rendering
• Contact Ids
• Simplify island merging
• Joint local transforms
• Toggle sensor with b2SensorEndTouchReason enum
• push and clip values on shapes for character movement
• Defer body waking to make more body functions thread-safe
• Add max force/torque to weld joint
• Motor joint sucks
• Sample with b2Body_IsValid before b2DestroyBody
• Luxo lamp sample
• deferred restitution
• optional skin radius to reduce ghost collisions
• rename weld joint to flex joint for clarity
• document how to glue and split bodies
• time step of 0 still does collision

I think gears should just be geometry now. Pulleys could use chains like the gate demo.

Option for text, add these two functions to my imgui_user.xxx

void ScreenText( const ImVec2& Pos, ImU32 Col, const char* Format, ... )
    {
    va_list Args;
    va_start( Args, Format );
    ScreenTextV( Pos, Col, Format, Args );
    va_end( Args );
    }

void ScreenTextV( const ImVec2& Pos, ImU32 Col, const char* Format, va_list Args )
    {
    char Text[ 512 ];
    vsprintf_s( Text, Format, Args );

    ImGuiViewport* Viewport = ImGui::GetMainViewport();
    ImDrawList* DrawList = ImGui::GetBackgroundDrawList( Viewport );
    DrawList->AddText( IMGUI_FONT_REGULAR_BOLD, 0.0f, Viewport->WorkPos + Pos, Col, Text );
    }
