refine external texture management #311

Closed zhuxingwei closed 2 years ago

zhuxingwei commented 2 years ago

In this PR we try to refine the management of external textures for Texture widgets by adding the functionality of an ExternalTextureRegistry to the UIWidgetsPanelWrapper, including:

(1) cache the (external texture)-(internal texture id) mapping so that an external texture is only registered on the C++ side once (2) unregister the external textures on the C++ side when the UIWidgets panel is destroyed
