| width | New width of the Texture. |
| height | New height of the Texture. |
| format | New format of the Texture. |
| hasMipMap | Indicates if the Texture should reserve memory for a full mip map chain. |
bool Returns true if the reinitialization was a success.
Reinitializes the Texture to width by height, format to format and optionally creates mip maps.
After reinitializing, Texture pixels will be undefined. This function is very similar to the Texture constructor,
except it works on existing Texture object.
Call Apply to actually upload the changed pixels to the graphics card.
The Texture has to have read/write enabled flag set in the texture import settings.
