 		<member name="enable_alpha_to_coverage" type="bool" setter="set_enable_alpha_to_coverage" getter="get_enable_alpha_to_coverage" default="false">
+			If [code]true[/code], alpha to coverage is enabled. This generates a temporary coverage value based on the alpha component of the fragment's first color output. This allows alpha transparency to make use of multisample antialiasing.

 		<member name="enable_alpha_to_one" type="bool" setter="set_enable_alpha_to_one" getter="get_enable_alpha_to_one" default="false">
+			If [code]true[/code], alpha is forced to either [code]0.0[/code] or [code]1.0[/code]. This allows hardening the edges of antialiased alpha transparencies. Only relevant if [member enable_alpha_to_coverage] is [code]true[/code].

+			If [code]true[/code], enables per-sample shading which replaces MSAA by SSAA. This provides higher quality antialiasing that works with transparent (alpha scissor) edges. This has a very high performance cost. See also [member min_sample_shading].

+			The multiplier of [member sample_count] that determines how many samples are performed for each fragment. Must be between [code]0.0[/code] and [code]1.0[/code] (inclusive). Only effective if [member enable_sample_shading] is [code]true[/code]. If [member min_sample_shading] is [code]1.0[/code], fragment invocation must only read from the coverage index sample.
