a2518493a2 gl renderer: Fix color matrix shader 
We *just* computed a un-premultiplied color, maybe we should also use
it.

4869013a8d gl renderer: Fix coloring shader 
We *just* pre-multiplied u_color but then didn't use its rgb values.
This fixes backdrop scale marks in Adwaita to not be white.

eaf899061a gl renderer: Remove shadow program 
Drawing shadows is the same task as drawing text in our case and these
two shaders have been the same thing for quite a while.

d2b5436462 gl: Make blur nodes with radius ∈ ]0; 1[ 
Otherwise, the radius here ends up being 0 and we don't draw anything at
all.

4946810960 gl renderer: Render unblurred outset shadows differently 
We don't need to draw anything to a texure for those.

2bc10fa365 gl renderer: draw all outset shadows 
Instead of falling back to cairo for most of them.

7a2d30323e gl renderer: try doing outset box shadows 
Still fall back in cases we can't handle that way.

bed03aa319 gl renderer: Fix linear gradient shader color calculation 
This fixes both the wrong headerbar color and the broken border color in
of the circular button in the widget-factory.

eb221ff305 gl renderer: Only take glyph texture alpha into account 
This way, we can use the very same coloring program to draw text shadows
of fonts with colored glyphs.

the _location integers we save in every Program struct.

9048d40bc2 vulkan: Fix mask shader to premultiply color 
The inColor wasn't premultiplied, so the resulting colors were wrong
with translucent borders.

e1572e003a vulkan: No need to redefine gl_PerVertex 
The compiler has those predefined, so use them.

e4dbff6bfc vulkan: Delete unused shaders 
These have been renamed to .frag/.vert, apparently the originals weren't
deleted.

b564dd853c Avoid super-luminous pixels 
The color-matrix shader was creating pixels with r,g,b > a in
some cases, which leads to unexpected test failures. In particular
this as visible the opacity render node test for opacity 0.

76aa237cce Fix blendmode shader 
My reading of the spec formulas was imperfect.

5577fde990 vulkan: Rename blend pipeline to texture 
This is what it does, and the name blend is easily
confused with blend-mode.

485470511f vulkan: Update the outset-shadow fragment shaders 
These were missing the blur-radius parameter that is written
by the vertex shader, causing Vulkan validation to complain.

3c98b90fc6 vulkan: Implement nonseparable blendmodes 
This is a directly-from-the-spec, unoptimized implementation.

d61f6ff393 vulkan: Implement blend modes 
This is another example for a 2-texture shader.
So far, only separable blend modes are implemented.
The implementation is not optimized, with an
if-else cascade in the shader.
