- * We may use this function to reduce a large pixmap to a small sub
- * pixmap. Two scenarios currently:
- * 1. When fallback a large textured pixmap to CPU but we do need to
- * do rendering within a small sub region, then we can just get a
- * sub region.
- *
- * 2. When uploading a large pixmap to texture but we only need to
- * use part of the source/mask picture. As glTexImage2D will be more
- * efficient to upload a contingent region rather than a sub block
- * in a large buffer. We use this function to gather the sub region
- * to a contingent sub pixmap.
- *
- * The sub-pixmap must have the same format as the source pixmap.
