Matthew Kilgore cdbfb94c61 Fix GLUT redraw timing 
Currently the GLUT thread draws the screen too slowly, Ex. The default
is supposed to be 60 FPS, but it will always draw a bit slower than 60
FPS. This is because the current logic simply inserts delays for the
entire length of a frame, not taking into account how long it took us to
render the last frame.

The new code uses GetTicks() to measure how much time has passed since
the last render, which then lets us calculate the exact amount of delay
until the next frame. We additionally then measure how long the delay
lasted vs. what we asked for (since any delay we do only has a minimum
guarentee, it will ocassionally last a bit longer) and adjust based on
that as well. The result is a perfect 60 FPS as long as rendering is
quick enough.

If the rendering falls behind (Ex. a slow _GL SUB is in the program)
then we'll start skipping frames to get back on track.

Fixes: #408

/*
mem_static uses a pointer called mem_static_pointer to allocate linear memory.
It can also change mem_static_pointer back to a previous location, effectively erasing
any memory after that point.
Because memory cannot be guaranteed to be allocated in exactly the same location
after realloc which QB64 requires to keep functionality of previous pointers when
the current block of memory is full QB64 creates an entirely new block, much larger
than the previous block (at least 2x), and "writes-off" the previous block as un-
reclaimable memory. This tradeoff is worth the speed it recovers.
This allocation strategy can be shown as follows: (X=1MB)

XXXX

Aspect ratio determination:
32/256 modes always assume 1:1 ratio
All other modes (1-13) determine their aspect ratio from the destination surface's dimensions (presuming it is stretched onto a 4:3 ratio monitor)
Reference:
Line-drawing and cursor-movement commands:
D[n%] Moves cursor down n% units.
E[n%] Moves cursor up and right n% units.
F[n%] Moves cursor down and right n% units.
G[n%] Moves cursor down and left n% units.
H[n%] Moves cursor up and left n% units.
L[n%] Moves cursor left n% units.
M[{+|-}]x%,y% Moves cursor to point x%,y%. If x% is preceded
by + or -, moves relative to the current point.
-+/- relative ONLY if after the M, after comma doesn't affect method
-nothing to do with VIEW/WINDOW coordinates (but still clipped)
R[n%] Moves cursor right n% units.
U[n%] Moves cursor up n% units.
[B] Optional prefix that moves cursor without drawing.
[N] Optional prefix that draws and returns cursor to
its original position.
*Prefixes B&N can be used anywhere. They set (not toggle) their respective states. They are only cleared if they are used in a statement. They are
forgotten when a new DRAW statement is called. Color, rotation, and scale commands: An% Rotates an object n% * 90 degrees (n% can be 0, 1,
2, or 3).
Cn% Sets the drawing color (n% is a color attribute).
Pn1%,n2% Sets the paint fill and border colors of an object
(n1% is the fill-color attribute, n2% is the
border-color attribute).
Sn% Determines the drawing scale by setting the length
of a unit of cursor movement. The default n% is 4,
which is equivalent to 1 pixel.
TAn% Turns an angle n% degrees (-360 through 360).
-If you omit n% from line-drawing and cursor-movement commands, the
cursor moves 1 unit.
-To execute a DRAW command substring from a DRAW command string, use
the "X" command:
DRAW "X"+ VARPTR$(commandstring$)
