Description

getGradientTexture():
could save some work if we converted the *GradientContext classes to produce ByteRgbaPre data instead of IntArgbPre data...
Comments
As noted above, this JBS issue describes two separate issues: * The first is a TODO that says we "need to dispose...when the context is disposed". This was fixed as part of JDK-8239589. * The second is a possible performance enhancement noted in a TODO comment that we could save some work if we converted the *GradientContext classes to produce ByteRgbaPre data instead of IntArgbPre data. This JBS issue will track the latter of these.

The first part of this issue, disposing the cache when context is disposed, will be addressed by the fix for JDK-8239589. Once that bug fix is integrated, I will update this RFE to track only the second issue, optimize getGradientTexture.
