```
    Description copied from interface: IPainter
    Stenciling, like depth-buffering, enables and disables drawing on a per-pixel basis. Stencil planes are first drawn into using GL drawing primitives, then geometry and images are rendered using the stencil planes to mask out portions of the screen. Stenciling is typically used in multipass rendering algorithms to achieve special effects, such as decals, outlining, and constructive solid geometry rendering. The stencil test conditionally eliminates a pixel based on the outcome of a comparison between the reference value and the value in the stencil buffer. To enable and disable the test, call glEnable and glDisable with argument GL_STENCIL_TEST. To specify actions based on the outcome of the stencil test, call glStencilOp or glStencilOpSeparate. There can be two separate sets of func, ref, and mask parameters; one affects back-facing polygons, and the other affects front-facing polygons as well as other non-polygon primitives. glStencilFunc sets both front and back stencil state to the same values. Use glStencilFuncSeparate to set front and back stencil state to different values. func is a symbolic constant that determines the stencil comparison function. It accepts one of eight values, shown in the following list. ref is an integer reference value that is used in the stencil comparison. It is clamped to the range 0 2 n - 1 , where n is the number of bitplanes in the stencil buffer. mask is bitwise ANDed with both the reference value and the stored stencil value, with the ANDed values participating in the comparison. If stencil represents the value stored in the corresponding stencil buffer location, the following list shows the effect of each comparison function that can be specified by func. Only if the comparison succeeds is the pixel passed through to the next stage in the rasterization process (see glStencilOp). All tests treat stencil values as unsigned integers in the range 0 2 n - 1 , where n is the number of bitplanes in the stencil buffer. The following values are accepted by func:
    
    GL_NEVER Always fails.
    GL_LESS Passes if ( ref & mask ) < ( stencil & mask ).
    GL_LEQUAL Passes if ( ref & mask ) <= ( stencil & mask ).
    GL_GREATER Passes if ( ref & mask ) > ( stencil & mask ).
    GL_GEQUAL Passes if ( ref & mask ) >= ( stencil & mask ).
    GL_EQUAL Passes if ( ref & mask ) = ( stencil & mask ).
    GL_NOTEQUAL Passes if ( ref & mask ) != ( stencil & mask ).
    GL_ALWAYS Always passes.
    Specified by:
    
    glStencilFunc in interface IPainter
    
    Parameters:
    
    func - sets the stencil test function that determines whether a fragment passes or is discarded. This test function is applied to the stored stencil value and the glStencilFunc's ref value. Possible options are: GL_NEVER, GL_LESS, GL_LEQUAL, GL_GREATER, GL_GEQUAL, GL_EQUAL, GL_NOTEQUAL and GL_ALWAYS. The semantic meaning of these is similar to the depth buffer's functions.
    
    ref - specifies the reference value for the stencil test. The stencil buffer's content is compared to this value.
    
    mask - specifies a mask that is ANDed with both the reference value and the stored stencil value before the test compares them. Initially set to all 1s.
  - glStencilMask
```
public void glStencilMask(int mask)
```
    Description copied from interface: IPainter
    
    glStencilMask controls the writing of individual bits in the stencil planes. The least significant n bits of mask, where n is the number of bits in the stencil buffer, specify a mask. Where a 1 appears in the mask, it's possible to write to the corresponding bit in the stencil buffer. Where a 0 appears, the corresponding bit is write-protected. Initially, all bits are enabled for writing. There can be two separate mask writemasks; one affects back-facing polygons, and the other affects front-facing polygons as well as other non-polygon primitives. glStencilMask sets both front and back stencil writemasks to the same values. Use glStencilMaskSeparate to set front and back stencil writemasks to different values.

```
    Description copied from interface: IPainter
    
    The glStencilOp(GLenum sfail, GLenum dpfail, GLenum dppass) contains three options of which we can specify for each option what action to take:
    Specified by:
    
    glStencilOp in interface IPainter
    
    Parameters:
    
    fail - action to take if the stencil test fails.
    
    zfail - action to take if the stencil test passes, but the depth test fails.
    
    zpass - action to take if both the stencil and the depth test pass. Then for each of the options you can take any of the following actions:
    
    Action : Description
    GL_KEEP : The currently stored stencil value is kept.
    GL_ZERO : The stencil value is set to 0.
    GL_REPLACE : The stencil value is replaced with the reference value set with glStencilFunc.
    GL_INCR : The stencil value is increased by 1 if it is lower than the maximum value.
    GL_INCR_WRAP : Same as GL_INCR, but wraps it back to 0 as soon as the maximum value is exceeded.
    GL_DECR : The stencil value is decreased by 1 if it is higher than the minimum value.
    GL_DECR_WRAP : Same as GL_DECR, but wraps it to the maximum value if it ends up lower than 0.
    GL_INVERT : Bitwise inverts the current stencil buffer value.

    NOT SUPPORTED in jGL wich emulate OpenGL 1 only. Note that are NOT triggered to ease compatibility with geometries that have the polygon offset fill setting enabled by default. Was added to OpenGL 2 (https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glPolygonOffset.xhtml). You may desactivate offset fill with drawable.setPolygonOffsetFillEnable(false).
