 [Fixed Bugs and Problems]

• Fixed a bug that could cause anomalies in drawing when using a brush of type "Water" with a moisture content of 1% or more on a layer with Alpha Lock enabled.
• Fixed a bug that when Jitter Color is enabled, brushes of type "Water" with 0% color mixing, 0% water content, and 1% or more color spread may not be treated as water.
• Fixed a bug in which brushes less than 48px may be drawn incorrectly when the aspect ratio is set to a value other than 0 and there are rotation patterns such as Initial Angle, Following Rotation, Jitter Angle.

• When the blending mode "Eraser" was selected for Brush tool, the color of the opacity groove was the selected drawing color, but this color is not reflected, so it was corrected to show black, similar to Eraser tool, etc.
