Enable perspective if rendering a single polygon.
Added Bresenhem's integer line drawing algorithm in gpLine...but this draws an entirely new image.
Will expand on this later for scan conversion. Works for steep and non-steep lines.
Merge branch 'master' of github.com:molohov/gpu2
Add prof target to Makefile.
Move line test into main directory. Fix swap (also need to swap y's!). Update Makefile so make prof doesn't mess up object files.
Check that image pixel is in the image before writing it.
Add more test cases for line.c. They didn't all pass, so I implemented Bresenham's line algorithm under http://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm#Simplification.
Check horizontal and vertical lines in line test.
Allow the board version to not wait on user pressing a key to draw the next image.
Fix Figure #.
