Recently, the grease pencil team has received some requests about the name of the tool. The current name using "//grease//" word in its name is confused and can transmit a wrong idea.
After some meeting, we agreed that we could change the name, but only slightly, because there was a big work for several years to create an image in the market.
As we are using internally in all areas of code the "gpencil" prefix already, the main change would be at UI level.
Our proposal is rename "Grease Pencil" to "GPencil", but there are some topics to decide.
1) Rename to "**GPencil**" or "**Gpencil**". We think the use of two capitals is better because transmit something like "Graphic Pencil". If we use only one capital letter, it looks we want emphasize only the "G".
2) What to do with python API. Actually, a lot of code is done using "**grease_pencil**" (bpy.data.grease_pencils).
