|
|
* - For swizzled texture row pitch is texture width X pixel/block size. There's not padding between row.

|

|

* The template iterates over all depth (including cubemap) and over all mipmaps.
|

* Sometimes texture provides a pitch even if texture is swizzled (and then packed) and in such case it's ignored. It's passed via suggested_pitch and is used only if padded_row is false.
