#332 More patches from my fork

[Mercury233]

Here are some additional patches:

1. Add EMIE_LMOUSE_DOUBLE_CLICK and EMIE_LMOUSE_TRIPLE_CLICK support on macOS.
2. Fix zlib decompression:
   Fix calling inflateEnd twice
   Prevent forced setting err to OK
3. Fix PressedImage handling in CGUIButton
PressedImage was set in setImage but was not updated when setImage was called again.
   This change aligns the behavior with version 1.9.
4. Backport [r5827]
5. Fix CImageLoaderJPG support for CMYK (YCCK):
   The color space of CMYK JPG files saved in Photoshop may be YCCK
   Fix the color order
   Avoid using floating-point operations, since the conversion is already approximate

Patches 1 and 2 should also apply to the trunk, and the trunk already includes part of patch 5.

An AI-generated sample image and its CMYK version are also attached.

Oh I forgot this, it should apply to trunk as well.

• fix CGUITabControl scroll buttons persist after resize
  The scroll control buttons remained visible after resizing the tab control larger and fit in viewport. CurrentScrollTabIndex was not reset when needScrollControl() returned false, causing the OR condition to remain true if user had scrolled previously.
