coverage value. The value is clamped to the range 0 1. The initial value is
1.0.

Specify a single boolean value representing if
the coverage masks should be inverted. GL_TRUE and GL_FALSE are
accepted. The initial value is GL_FALSE.
DESCRIPTION¶
Multisampling samples a pixel multiple times at various implementation-dependent subpixel locations to generate antialiasing effects. Multisampling transparently antialiases points, lines, polygons, and images if it is enabled.NOTES¶
The type of the value parameter was changed from GLclampf to GLfloat. This change is transparent to user code and is described in detail on the removedTypes() page.ASSOCIATED GETS¶
