- Field Detail
  - doubleBuffer
```
public boolean doubleBuffer
```
    Specifies a double-buffered surface. During context creation, only double-buffered formats are considered when set to true.
  - stereo
```
public boolean stereo
```
    Specifies a stereo surface. During context creation, only stereo formats are considered when set to true.
  - redSize
```
public int redSize
```
    The size in bits of the color buffer's red channel. During context creation, this specifies the minimum required red bits.
  - greenSize
```
public int greenSize
```
    The size in bits of the color buffer's green channel. During context creation, this specifies the minimum required green bits.
  - blueSize
```
public int blueSize
```
    The size in bits of the color buffer's blue channel. During context creation, this specifies the minimum required blue bits.
  - alphaSize
```
public int alphaSize
```
    The size in bits of the color buffer's alpha channel. During context creation, this specifies the minimum required alpha bits.
  - depthSize
```
public int depthSize
```
    The size in bits of the depth buffer. During context creation, the smallest depth buffer of at least the specified value is preferred, or zero for no depth buffer.
  - stencilSize
```
public int stencilSize
```
    The desired number of stencil bitplanes. During context creation, the smallest stencil buffer of at least the specified value is preferred, or zero for no stencil buffer.
  - accumRedSize
```
public int accumRedSize
```
    The size in bits of the accumulation buffer's red channel. During context creation, this specifies the minimum required red bits.
  - accumGreenSize
```
public int accumGreenSize
```
    The size in bits of the accumulation buffer's green channel. During context creation, this specifies the minimum required green bits.
  - accumBlueSize
```
public int accumBlueSize
```
    The size in bits of the accumulation buffer's blue channel. During context creation, this specifies the minimum required blue bits.
  - accumAlphaSize
```
public int accumAlphaSize
```
    The size in bits of the accumulation buffer's alpha channel. During context creation, this specifies the minimum required alpha bits.
  - sampleBuffers
```
public int sampleBuffers
```
    The number of multisample buffers used by this context. During context creation, this specifies the minimum number of multisample buffers requested.
  - samples
```
public int samples
```
    The number of samples accepted in the multisample buffer. During creation, pixel formats with the smallest number of samples that meets or exceeds the specified minimum number are preferred.
  - shareContext
```
public GLCanvas shareContext
```
    Another GLCanvas whose texture namespace and display lists should be shared.
