==Texture Layout Packing Strategies==
There are two strategies for packing the layout textures: using a resizable layout or using a fixed layout.
If we select the resizable layout strategy we will decide the size of the layout grid. However, if during the packig process some blocks don't fit in the layout, the size of the layout will be increased.
If we select this strategy we will decide the size of the maximum size of the layout grid. Like in the other strategy, if during the packig process some blocks don't fit in the layout, the size will be increased until the maximum layout size. If we still have some blocks that don't fit in the layout, then the size of the blocks will be reduced.
====Block Size Reduction====
Now the blocks have a new property called "Priority". This priority will decide which blocks will be reduced first if we can't increase the size of the layout.
