 Various fancy shaders for GZDoom ported from MariENB.

-
-Control over RGB gamma/intensity, along with a "tint" filter that, with a
-negative intensity, can also be used as a color booster (dunno how this even
-works, I wrote it 7 years ago lol). On top of all that, you can also do the

-### Color Matrix
-
-General purpose color mixing. The matrix is normalized in post. For experienced
-users.
-
-### Hue-Saturation
-
-The GIMP filter in shader form. Allows shifting the hue and tweaking the
-saturation and value of red, yellow, green, cyan, blue and magenta ranges.
-
-### Curves (TODO)
-
-8-point curve filter with cubic interpolation. Works just like the GIMP filter,
-with curves for value, red, green and blue.

-### BlurSharpShift

-Blurring followed by sharpening, followed by chromatic aberration. This is a
-meme filter chain that a lot of people love for some reason, claiming it adds

+### LUT Grading
+
+Premade lookup tables to alter color, all from the various MariENB editions I've made. More specialized LUTs will be added in the future.

+## Missing Shaders
+
+### Bloom
+
+It's very unlikely that this one will be added, unless I can hack something horribly using camera textures, idk.
+
+### Depth of Field
+
+Not a chance, this thing very blatantly needs Depth Buffer access, which is impossible in GZDoom thanks to portal rendering.
+
+### Tonemap
+
+Not needed, GZDoom implements its own.
+
+### Screen Frost / Heat Haze
+
+These aren't "general purpose" enough to be included.
+
+### Paint Filter
+
+Might add it, maybe???
+
+### SMAA
+
+This needs to be part of GZDoom, honestly.
