--
-- == Description
--
-- This extension adds some line rasterization features that are commonly
-- used in CAD applications and supported in other APIs like OpenGL.
-- Bresenham-style line rasterization is supported, smooth rectangular
-- lines (coverage to alpha) are supported, and stippled lines are
-- supported for all three line rasterization modes.

-- == New Commands

-- -   'cmdSetLineStippleEXT'
--
-- == New Structures

--
-- -   Extending

--
-- == New Enum Constants
--
-- -   'EXT_LINE_RASTERIZATION_EXTENSION_NAME'
--
-- -   'EXT_LINE_RASTERIZATION_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.DynamicState.DynamicState':

--
-- == Issues
--
-- > (1) Do we need to support Bresenham-style and smooth lines with more than
-- > one rasterization sample? i.e. the equivalent of glDisable(GL_MULTISAMPLE)
-- > in OpenGL when the framebuffer has more than one sample?
--
-- > RESOLVED: Yes.
-- > For simplicity, Bresenham line rasterization carries forward a few
-- > restrictions from OpenGL, such as not supporting per-sample shading, alpha
-- > to coverage, or alpha to one.
