All the children will be rendered into textures (if they aren't already
GskTextureNodes, which will be used directly). These textures will be
sent as input to the shader.
If the renderer doesn't support GL shaders, or if there is any problem
when compiling the shader, then the node will draw pink. You should use
gsk.glshader.GLShader.compile to ensure the shader will work for the
renderer before using it.
Creates a gsk.render_node.RenderNode that will render the given shader into the area given by bounds.
The args is a block of data to use for uniform input, as per types and offsets defined by the shader. Normally this is generated by gsk.glshader.GLShader.formatArgs or gsk.shader_args_builder.ShaderArgsBuilder.
See gsk.glshader.GLShader for details about how the shader should be written.
