“Straight Line from Last Point” behave wrong with sensitive pressure

The bug:

When using a pressure sensitive device and the pencil tool, line traced are glitched and their brush size is a size gradient from the current brush size to 1px. This is buggy, sometime, depending if the line is co-linear with an axe X or Y, there’s no problems and I’m getting a like of 1px thick. It is present from at least version 1.3 and that is starting to make me going nuts. I was expecting it gets fixed eventually, but maybe not everybody works with a stylus.

To reproduce:

  1. You need to use a pressure sensitive device like a Wacom tablet.
  2. Using the Pencil Tool
  3. Set the Brush size to something like 7
  4. Activate Pressure/Size analog option on the tool.
  5. Put a pixel anywhere, and then hold shift to make a line from last point.

Expected :
Either one of the following behavior:

  1. A line of the thickness of the brush size, ignoring pressure
  2. A line of 1px
  3. A line of the thickness given by the pressure at the end.
  4. The fancy option, a line where the thickness changes from the pressure at the start to the pressure at the end. (That is fancy and I don’t think it would be very intuitive or useful).

Any cases above is better than the current behavior. Or at least, please, add ways to set a keyboard shortcut for enabling/disabling the pressure/velocity options…
