This enumeration lists all the defined calls to a BLOBS compatible host
the host manages a screen, and divides it into viewports, where each viewport can be accessed independently

this attempts to create a viewport
The location of the viewport is indeterminate, as well as actual visibility. If the viewport can not be made visible in its entirety, the interface should provide a means to the user to bring it to the foreground.
The implementation defines the limitations of when a viewport can be created, which may mean that creation can be refused if viewports are already present. The implementation should at minimum support one viewport the size of the screen or less.
The implementation may interpret the input size in any linear system instead of pixels, such as characters. Consequently the actual size in pixels may be not be specified exactly but only as a multiple of a certain value. You should call <BLOBS_WINDOWDIMENSIONS> to retrieve the scaling involved

This enumeration lists all the defined calls to a BLOBS compatible viewport.
These can be roughly divided into two categories: graphics primitives, and helper functions.

Call index for character streams
This call emulates the effect of a console. Characters are emitted in order, wrapping around the ends of the screen. Special characters like newline or linefeed \n and \r work as they would on an printer, meaning that you have to emit both characters to continue at the start of the next line.
