ContextMode

Describes the map context mode. We can make some optimizations if we know that the drawing context is not shared with other code.

Entries

UNIQUE

Unique context mode: in OpenGL, the GL context is not shared, thus we can retain knowledge about the GL state from a previous render pass.

SHARED

Shared context mode: in OpenGL, the GL context is shared with other renderers, thus we cannot rely on the GL state set from a previous render pass.
