// Rules:
// 1. Arrays always start on .x
// 2. When placing a scalar or vector, search through the allocated slots for space *vertically*
//    (So check if you can place at o1.y, then o2.y, o3.y before o1.z, o2.z, etc.)
// 3. Elements with different interpolation cannot share a slot.
// 4. The first field of a struct is always aligned.

% The point of this test is to check that signature masks are handled correctly
% when they are not contiguous, so we attempt reading only component .xw from
% `color'. This happens when the shader is compiled by native, but not by us,
% currently, so it's not very useful for the moment. I'm leaving it anyway
% so that it either becomes useful when our HLSL compiler becomes more optimized
% or can be eventually rewritten in assembly/bytecode when the shader runner
% supports that.
