Convert 2D Pixel Position into Single Integer Index

The formula to convert the position of a pixel on a texture into an index is index = y*texture_width +x.

assume texture_width = 10
[FIRST ROW]
index = 0*10 + 0 -> index = 0
index = 0*10 + 1 -> index = 1
...
[SECOND ROW]
index = 1*10 + 0 -> index = 10
...
