fix res-independent-scanlines on non-vulkan drivers

Browse Source 
The imageSize parameter was getting mis-detected as a built-in uniform (that is, the dimensions of an image/framebuffer named 'image'), and this was causing d3d drivers to fail to compile altogether and glcore was giving back a 0/undefined value.

Closes #542.
