For a long time, VVVVVV has had an issue where if you used custom
graphics with translucent pixels (i.e. pixels whose opacity was neither
0% nor 100%, but somewhere between 0% and 100%), those pixels would end
up looking very ugly. They seemed to be overlaid on top of some weird
blue color, instead of actually being translucent.
This bug only occurred when in-game and not in towermode. So, most of
the time, basically. The translucent pixels only displayed properly
inside the Tower, both minitowers, and the editor (when not
playtesting).
I traced this down to the use of the magic number 0xDEADBEEF in
Graphics::drawmap() and Graphics::drawfinalmap(). Looks like someone had
fun finding a color. Was it you, simoroth? Anyway, I've changed it so it
simply uses 0 instead. Note that this magic number needs to be changed
for BOTH FillRect() and OverlaySurfaceKeyed(), or else the game's
background will be some random solid color instead of actually being
drawn properly.
This uncomments the code for the font outline. Now, you will see the
font outline on text that had it in the Flash version, most notably "-
Press ENTER to Teleport -" and the time trial overlay text.
This also fixes a problem with the commented code, where un-centered
text didn't outline properly.
This is similar to what was reverted in 3011911 but this time should use
syntax available even before C++11, tested on Clang with
`-std=c++98 -Wall -pedantic`.
