/**
 * Native bindings to the AMD_sample_positions extension.
 * 
 * This extension provides a mechanism to explicitly set sample positions for a FBO with multi-sampled attachments. The FBO will use identical sample
 * locations for all pixels in each attachment. This forces TEXTURE_FIXED_SAMPLE_LOCATIONS to TRUE if a multi-sampled texture is specified using
 * TexImage2DMultisample or TexImage3DMultisample. That is, using GetTexLevelParameter to query TEXTURE_FIXED_SAMPLE_LOCATIONS will always return TRUE if
 * the mechanism is explicitly used to set the sample positions.
 * 
 * Requires {@link GL32 OpenGL 3.2} or {@link EXTFramebufferMultisample EXT_framebuffer_multisample}.
