/*
	Per-GPU type settings.
	
	Supported settings:
		default_shader_level	Shader level used if user hasn't made a choice.
								Default: "SHADERS_FULL". Possible values:
								"SHADERS_OFF", "SHADERS_SIMPLE", "SHADERS_FULL".
		maximum_shader_level	Maximum permitted shader level. Same values as
								above. Default: "SHADERS_FULL". If set to
								"SHADERS_OFF", shaders are treated as not
								available.
		smooth_points			Enable or disable use of point smoothing.
								Default: true.
		smooth_lines			Enable or disable use of line smoothing.
								Default: true.
		use_dust_shader			Enable or disable use of vertex shader for
								dust effect. (This is inefficent on systems
								where vertex shaders are run on the CPU.)
								Default: true.
		texture_units			Number of texture units available to fixed-
								function multitexturing. Default (and maximum):
								defined by OpenGL implementation. Can be
								queried in debug console as:
								console.glFixedFunctionTextureUnitCount
								Oolite currently won't use more than two
								texture units.
		texture_image_units		Number of texture samplers usable in fragment
								shaders. Default (and maximum): defined by
								OpenGL implementation. Can be
								queried in debug console as:
								console.glFragmentShaderTextureUnitCount
	
	Other keys:
		match					Defines the conditions in which the settings
								dictionary is used; see "Matching dictionaries"
								below.
		precedence				Affects the order in which settings
								dictionaries are considered. Higher precedence
								dictionaries are considered before lower ones.
								The default precedence is 1.
	
	Matching dictionaries:
		"match" dictionaries contain regular expressions tested against any of
		"vendor", "renderer", "version" and "extensions". These are displayed
		near the top of the log by default. Note that "version" here refers to
		the full version string (shown in parentheses). The "extension" string
		used for matches is space-separated (no commas as in the log), and
		extension strings may occur in any order.
		Multiple regexps may be specified as an array, in which case all must
		match.
		Any backslashes in regexps must be escaped (i.e., doubled).
