Application UI design

1.1 To display the picture on the screen, I will use the opengl DGL library. To do this, I will create a component that will store the entire set of functions for displaying and editing a raster.

 1.2 The application must support multiple files. Since only one oppengl context can be created in the application, the form for displaying the image will be one, but there will be bookmarks for other images
