Expected Behavior

The descenders (the part of a letter "below the line") is cut off when specifying a wrap_at point within the text() command. With the wrap_at variable omitted, the descender reappears.

from p5 import *

f = None

def setup():
        global f
        size(640, 480)
        # Create the font
        f = create_font("Arial.ttf", 20)
        text_font(f)

Other widgets like Sliders and Numberboxes submit their values and call events immediately when they are changed, but Textfield requires the extra step of pressing enter. This isn't always intuitive, especially when you're filling out a form with a list of text boxes -- most people won't press enter after typing in each one. If you are using linked variables to access the values (instead of `getTe

Issue description

while the example is correct, the documentation is wrong
Syntax curveTangent(a, b, c, d, t)

Parameters
a float: coordinate of first point on the curve
b float: coordinate of first control point
c float: coordinate of second control point
d float: coordinate of second point on the curve

Environment: Android 6.0
NOTE: This is in the test version from #24, I have not yet tested whether this would happen in the 0.4.0 release.
Attempting to open the sketch folder from within APDE (via android's native file browser) instead opens the "Recent" list as shown in the attachment.
This applies regardless of sketchbook location.

@gaocegege -- what are the current build instructions?

CONTRIBUTING.md says "Read the README.md for build instructions" -- but it doesn't have build instructions. I'm looking through various artifacts -- docker, travis, appveyor, a build.xml for ant (eclipse?), and a set of scripts, e.g. deploy -- and trying to reconstruct a build setup for when I roll up a new release.

Pinch gestures are used to zoom objects or views in and out. Pinching is used to modify the scale. This is a multiplicative operation, not an additive one. onPinch currently gives the difference in distance between the two contact points before and after the gesture, but doesn't tell anything about the size.

As an example, a 10-pixel difference between points starting 10 pixels apart would
