We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

<constants>
|
|
<constant name="OP_TYPE_SCALAR" value="0" enum="OpType">
|
|
A floating-point scalar.
|

</constant>
|
|
<constant name="OP_TYPE_VECTOR_2D" value="1" enum="OpType">
|
|
A 2D vector type.
|
|
</constant>
|
|
<constant name="OP_TYPE_VECTOR_3D" value="2" enum="OpType">
|
|
A 3D vector type.

<constant name="OP_TYPE_VECTOR_4D" value="3" enum="OpType">
|
|
A 4D vector type.
|

</constant>
|
|
<constant name="OP_TYPE_MAX" value="4" enum="OpType">
|
|
Represents the size of the [enum OpType] enum.
|
|
</constant>
|
|
<constant name="FUNC_SUM" value="0" enum="Function">
|
|
Sum of absolute derivative in [code]x[/code] and [code]y[/code].
|
|
</constant>
|
|
<constant name="FUNC_X" value="1" enum="Function">
|
|
Derivative in [code]x[/code] using local differencing.
|
|
</constant>
|
|
<constant name="FUNC_Y" value="2" enum="Function">
|
|
Derivative in [code]y[/code] using local differencing.
|
|
</constant>
|
|
<constant name="FUNC_MAX" value="3" enum="Function">
|
|
Represents the size of the [enum Function] enum.
|
|
</constant>
|
|
<constant name="PRECISION_NONE" value="0" enum="Precision">
|
|
No precision is specified, the GPU driver is allowed to use whatever level of precision it chooses. This is the default option and is equivalent to using [code]dFdx()[/code] or [code]dFdy()[/code] in text shaders.
|
|
</constant>
|
|
<constant name="PRECISION_COARSE" value="1" enum="Precision">
|
|
The derivative will be calculated using the current fragment's neighbors (which may not include the current fragment). This tends to be faster than using [constant PRECISION_FINE], but may not be suitable when more precision is needed. This is equivalent to using [code]dFdxCoarse()[/code] or [code]dFdyCoarse()[/code] in text shaders.
|
|
</constant>
|
|
<constant name="PRECISION_FINE" value="2" enum="Precision">
|
|
The derivative will be calculated using the current fragment and its immediate neighbors. This tends to be slower than using [constant PRECISION_COARSE], but may be necessary when more precision is needed. This is equivalent to using [code]dFdxFine()[/code] or [code]dFdyFine()[/code] in text shaders.
