Placing an image at atlas fails sometimes.

[slobodin]

Consider a bitmap with width equal to 1024.
Suppose, in TBBitmapFragmentManager::CreateNewFragment we fail to allocate this image in an existing atlas. So, we create a new atlas with width equal to nearest power of 2 of 1024 (which is 1024). So, we creating new TBBitmapFragmentMap and trying to place new bitmap into it (fm->CreateNewFragment). But this function adds a border of 2 pixels by default, so we fail to place new image here and the function returns null. As a result image is not displayed.
