/**

|
* GdkGLTextureBuilder:
|
|
*
|
|
* `GdkGLTextureBuilder` is a builder used to construct [class@Gdk.Texture] objects from
|
|
* GL textures.
|
|
*
|
|
* The operation is quite simple: Create a texture builder, set all the necessary
|
|
* properties - keep in mind that the properties [property@Gdk.GLTextureBuilder:context],
|
|
* [property@Gdk.GLTextureBuilder:id], [property@Gdk.GLTextureBuilder:width], and
|
|
* [property@Gdk.GLTextureBuilder:height] are mandatory - and then call
|
|
* [method@Gdk.GLTextureBuilder.build] to create the new texture.
|
|
*
|
|
* `GdkGLTextureBuilder` can be used for quick one-shot construction of
|
|
* textures as well as kept around and reused to construct multiple textures.
|
|
*
|
|
* Since: 4.12
