This sets up a few different flags we'll need for the conditional
compiling, and also sets the C++ standard to gnu++11, which effectively
just matches what we were implicitly using before.
Mostly old build scripts and helper files that are now covered by the
Makefile.
A notable deletion is the glew dll and lib files. These are unnecessary
because we compile `glew.c` directly rather than link against the dll or
lib copies we have.
Having windows call GetSystemMetrics without relying on glutGet, gets rid of the seg fault that can occur at program start up. screenicon was restored to it's previous state so that larger issues with it can be addressed at a future date.
Fixes the issue as brought up on the forums here: https://qb64phoenix.com/forum/showthread.php?tid=408
Also added a small set of logic so we don't end up inside an endless loop if the screen is hidden (via _SCREENHIDE), or if it doesn't exist for whatever reason.
Currently there is a bug where if a variable width font is in use and
text printed would exactly fit to the end of the row, it is instead
wrapped and printed on the next line.
Ex. You're printing a character that is 10 pixels wide, starting
from position 90 on an image that is 100 pixels wide. This should fix,
but instead your character will be printed on the next line.
The reason this happens is an off by one error, cursor_x (effectively
the X value passed to LOCATE) is one based even when using a variable
width font where cursor_x represents a pixel location. The location that
check if the next character can fit on the screen never handles the base
one, so it ends up treating the ending Y coordinate as one past where it
will actually end, which makes the code thing the print will go past the
edge of the screen.
To fix we simply subtract one before doing the comparison to give us the
actual ending pixel column.
internal/c/c_compiler no longer contains anything, so git will not
create it. This change makes setup_win.bat create the directory if it's
not already there.
