|

* 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.
