Le Philousophe 4598da7ec1 TINYGL: Add opaque support to RLE blitting routine 
This fixes Myst3 transitions.
Before commit 5cc4607ff4, opaque images had a list of lines generated
covering the whole image.

Le Philousophe 71ba2fc12d TINYGL: Unify clipping rectangles and use a proper name 
Clipping is not scissor.

D G Turner 4a5e96ce6f TINYGL: Fix GCC Warning for Implicit Copy Operator 
This is emitted when -Wdeprecated-copy is enabled. The fix implemented
is to explicitly declare this to be the default copy operator.

Since this may be a latent bug, this is marked with a FIXME.

Vincent Pelletier 009d3320b3 TINYGL: Compute surface pixel count once only in BlitImage::loadData 
Cartesian coordinates are not actually needed here, so simplify
computations by just using a pixel offset.

Vincent Pelletier eeedf4de06 TINYGL: Deduplicate PixelFormat retrieval in zblit 
For some reason, loadData hardcodes a pixel format.
At least avoid duplicating it in Line constructor.
Likewise, avoid duplicating access to framebuffer's pixel format when
constructing a Line from another.
Also, avoid over-allocating Line, as its size argument is counted in pixel,
not in bytes.

Vincent Pelletier bf319b5437 TINYGL: Cache and clip dirty rect on all DrawCall subclasses. 
getDirtyRegion will be called twice on each DrawCall instance, so make
repeated work as short as possible.

Vincent Pelletier 6087492dbd TINYGL: Simplify setting & disabling scissors. 2017-04-23 10:35:04 +00:00
Vincent Pelletier e1de3407f1 TINYGL: Make scissors follow Common::Rect semantics. 
As per Common::Rect data model, right and bottom border are excluded, so:
- Make FrameBuffer::scissorPixel reject bottom & right borders.
- Update bounding rectangle definition for dirty rectangle operations
  ClearBufferDrawCall::getDirtyRegion is already correct.
- zblit was almost following, except for an off-by-one mistake.

Vincent Pelletier 112ca82363 TINYGL: Manage BlitImages with a refcount. 
So that zdirtyrect can keep an image alive for longer than its creator
intended.

Vincent Pelletier 7c1a15c6e8 TINYGL: Expect colorKey in the same pixel format as surface. 
So caller does not have to depend on the pixel format used internally to
BlitImage.
Update callers which do request for color keying (GRIM/EMI only).
Also, remove a special-casing of transparent color when converting image
format which sets a color in a packed format independent from actual
destination format.
Also, in GfxTinyGL::createTextObject, prefer changing invisible colorKey
value than actually-visible color.
