107 * instead of boxing the texture :

113 * ----------------------------------- |
114 * | boxed empty | boxed empty | pow2height
116 * -----------------------------------
119 * we're repacking the data to the expected texture width
121 * |<-texture width ->| -->pow2width| /\
122 * |111111111111111111222222222222222| |
123 * |222333333333333333333444444444444| texture height
127 * | empty | pow2height

134 * |111111111111111111|

136 * |333333333333333333|
137 * |444444444444444444| \/
138 * --------------------
140 * this also means that any references to allocatedMemory should work with the data as if were a
141 * standard texture with a non-power2 width instead of texture boxed up to be a power2 texture.
143 * internally the texture is still stored in a boxed format so any references to textureName will
144 * get a boxed texture with width pow2width and not a texture of width currentDesc.Width.
146 * Performance should not be an issue, because applications normally do not lock the surfaces when
147 * rendering. If an app does, the SFLAG_DYNLOCK flag will kick in and the memory copy won't be released,
148 * and doesn't have to be re-read.
