Add benchmarks from 6.24.0.

Bump the version to 6.25.0 for the next release.

Note that the triangle turtle can be replaced with a rotating bitmap and that the editor supports some syntax coloring.

Fix some syntax coloring problem when braces, backets, or parens are preceeded by a backslash.

Fix some syntax coloring when text within a vbar contains escaped vbars.

Include turtle.bmp in the release.

Add a bitmap that resembles a turtle that is to be used in place of the triangle in a Sri Lankan school system.

Add some tests for trying grow a bitmap with BITFIT to something that is larger than it could reasonably allocate.

Used integral math, instead of floating point math, when interpolating RGB values, since the domain is so limited. This results in a small (1%) speed improvement.

Bypass the bilinear interpolation for sprite rendering if all adjacent pixels are identical. This yeilds a 10% speed gain when drawing squirals and circles.
