Interface of a Video Driver dependent Texture.
<p>
An <a class="el" href="classirr_1_1video_1_1_i_texture.html" title="Interface of a Video Driver dependent Texture.">ITexture</a> is created by an <a class="el" href="classirr_1_1video_1_1_i_video_driver.html" title="Interface to driver which is able to perform 2d and 3d graphics functions.">IVideoDriver</a> by using <a class="el" href="classirr_1_1video_1_1_i_video_driver.html#8c02ee280bb738cdf38b77e7a798244e" title="Creates an empty texture of specified size.">IVideoDriver::addTexture</a> or <a class="el" href="classirr_1_1video_1_1_i_video_driver.html#f4055165190e4adf221c6dc6f2434ea0" title="Get access to a named texture.">IVideoDriver::getTexture</a>. After that, the texture may only be used by this VideoDriver. As you can imagine, textures of the DirectX and the OpenGL device will, e.g., not be compatible. An exception is the Software device and the NULL device, their textures are compatible. If you try to use a texture created by one device with an other device, the device will refuse to do that and write a warning or an error message to the output buffer.

The texture is usually scaled, if it was created with an unoptimal size. For example if the size of the texture file it was loaded from was not a power of two.
