◆ m_bUseCanvasPanning

bool ocpnGLOptions::m_bUseCanvasPanning

Controls OpenGL canvas hardware-accelerated panning mode.

When true, uses an OpenGL optimization where the chart is rendered to a texture (via FBO - Frame Buffer Object) during panning operations. This texture is then translated/moved using GPU operations rather than redrawing the entire chart for each pan event, significantly improving performance during chart panning.

This is separate from standard chart panning which is enabled by default and uses left-click + drag. This flag only controls whether that panning uses hardware acceleration.
