Finally figured out how resource tables work
<alyssa>
so I can start making progress on gfx cmdstream
<HdkR>
\o/
<alyssa>
The attribute descriptor is changed, re-reversing
<alyssa>
Pixel format is in the same place, that's a start.
<alyssa>
Ooh, interesting, stride is now on the attribute descriptor.
<alyssa>
that, uh, makes things more annoying for opengl
<alyssa>
but maybe makes things easier for vulkan?
<alyssa>
meh, won't overthink it

tolszak: as an aside - it's more efficient on mali to use a vec3 position attribute and then do `gl_Position = vec4(attribute, 1.0)`
<alyssa>
instead of a vec4 with the 1.0 implied
<alyssa>
since in the former case, we optimize out the 1.0/w
<alyssa>
not relevant here but y'know
<tolszak>
alyssa: Pardon my ignorance in this area. It is just copy pasting from an example. I'd written perhaps one or 2 shaders in my life a few years ago.
<alyssa>
Sure
<tolszak>
alyssa: There is something interesting. Default GL_TEXTURE_MIN_FILTER is GL_NEAREST_MIPMAP_LINEAR
<tolszak>
alyssa: So when I comment out lines that set GL_NEAREST on MIN and MAG the screen is black

alyssa: My bad in docs it is explicitly stated that one should do the glGenerateMipmap(GL_TEXTURE_2D); when using default MIPMAP filtering. Anyways the issues is there, filtering is irrelevant
