This allows the Vulkan runner to execute in environments which do
not support geometry shaders, most notably MoltenVK. In particular,
that enables SM<4 shaders to run in such environments
This is simply unnecessary and wastes time.
As part of this, simply remove the "all" directive. Only for a couple of tests
is it even potentially interesting to validate all pixels (e.g.
nointerpolation.shader_test), and for those "all" is replaced with an explicit
(0, 0, 640, 480) rect.
In all other cases we just probe (0, 0).
On shader_test files, now resources should be declared this way:
[texture n] -> [srv n]
[srv buffer n] -> [srv n]
[uav n] -> [uav n]
[uav buffer n] -> [uav n]
[vertex buffer n] -> [vb n]
[render target n] -> [rtv n]
The dimension (buffer or 2D) is now specified as an additional parameter
in the "size" directive:
For 2D resources:
size (n, m) -> size (2d, n, m)
For buffers:
size (n, 1) -> size (buffer, n)
