-//! "Framebuffer" space represents the final destination of our rendeing,

-//!   - for rasterized primitives, the orthographics projection transforms
-//! the content rectangle to -1 to 1
-//!   - the viewport transformation is setup to map the whole range to
-//! the framebuffer rectangle provided by the document view, stored in `DrawTarget`
-//!   - all the direct framebuffer operations, like blitting, reading pixels, and setting
-//! up the scissor, are accepting already transformed coordinates, which we can get by
-//! calling `DrawTarget::to_framebuffer_rect`
