* Shader compilation failed with vertex, object and primitive ID
enabled due to the NO_GEOMETRY_SHADER define not being correctly
propagated
* Enabling just vertex ID visualization on WebGL caused an assert in
constructor, complaining that "at least one visualization feature has
to be enabled", which is wrong
* Defaults were not correctly set up for vertex ID rendering, causing
all-black render when setColor() wasn't called
* Forgot to list/bundle some ground truth test images for the test
case, causing the test to fail due to files not found
* The test asserted when generating mesh data due to an unhandled
corner case
* The test expected an ES2 assertion message on WebGL 2
* Flag::Wireframe now implicitly enables Flag::NoGeometryShader also on
WebGL. This was done only for ES2 previously, but WebGL doesn't have
(and won't have) geometry shaders, so it makes sense to do the same
there.
It was rendering everything with a plain color, which is rather useless.
Moreover it wasn't consistent with TBN visualization where you might
actually want only the lines rendered and not the triangle.
As usual, the old APIs are still present, but marked as deprecated.
Existing code is not updated yet to ensure I didn't break anything with
this.
This way it's much more intuitive and makes the code shorter and nicer
in many cases. Shaders are now also able to hide irrelevant
draw/dispatch APIs to avoid accidents.
I introduced *strong* enum with values, in a subnamespace, that have the
same name as completely unrelated typedefs. Guess what?! It breaks ALL
LINKS TO THOSE TYPEDEFS! **EVERYWHERE!!!**
Two reasons:
* documentation
* making it actually work because the rules are so complex and ever
changing that a thing I thought "just worked" in fact did not work at
all
The Vector tests now compile again.
Followup to previous commit -- links to opengl.org are now redirected to
khronos.org and the extension links have the same format for both GL and
GLES. That allows me to remove some of the Doxygen aliases and use just
a single set of the functions for both GL and GLES.
